Side by Side - Dolby Vision and Regular

[kfbkfb]

Example:
"Furious 8" includes a Dolby Vision UHD Blu-ray and
a regular Blu-ray.

Using a UHDTV and a UHD Blu-ray player, both with
Dolby Vision and the "Furious 8" UHD Blu-ray and a
HDTV with the regular "Furious 8" Blu-ray side by side,
synchronize playback and see, scene by scene,
if Dolby Vision makes that much of a difference.

if? :: what's your point?

'the difference is quite obvious', unless you're 'blind or biased'

i often compare (Dolby Vision & HDR10) using two identical players (same input and same cable) on an LG OLED C7P

furthermore, i also compare the SDR/HD disc copy on the same system

this is one of the many discs that i regularly use as i continue to compare

you seem to imply this is a difficult comparison (differences subtle) - i can assure you that the differences (each) are quite profound

Dolby Vision (picture quality) has no competition, as it is dramatically improved (resolution - color - contrast - naturalness - realism - viewing comfort)

note :: i, and a few friends that have HD displays did the same comparison(s) - (only - watching the (SDR/HD & HDR10/UHD) version(s) at their home, using one of my UHD players on loan - after watching the (Dolby Vision/UHD & HDR10/UHD & SDR/HD version(s) - here) - and, the outcome was as expected; it's Dolby Vision - if you care about picture quality, with the additional improvements that an UHD disc, although being played on an HD display, both noticed and appreciated

so, i am expecting controversy, which is sad

The LG OLED is why the difference is large for you, because it is underpowered in light output. If you compared on a Samsung set which exceeds the HDR10 recommended light output requirements the difference is much much smaller.

Dynamic metadata/DV most impacts HDTVs that truly can't fully meet HDR10 light output needs.

Of course it will make a difference - you're talking about comparing to a regular SDR Blu-ray. You'd be doing a comparison of SDR vs HDR.

A more meaningful comparison would be the same disc playing in HDR10 on one display and DoVi on the other.

[bruceames]

jibucha, don't get so worked up over the OP. It's obvious you're a huge fan of Dolby Vision, but the comparison was to be with a regular Blu, not a UHD using HDR10. Of course the difference will be large in that case.

Which 4k disc did you make this comparison with on your Samsung?

[RockyIII]

Comparing DV to HDR10 the difference on my Oled C6 is close to 0. Both look great.

My previous display had both HDR10 and Dolby Vision compatibility. I would regularly compare the two and found very small differences, at least on the display I used. I should note that the DV content was streaming via VUDU as my 4K player does not output DV. Because of the generally sharper appearance of the disc, I usually went that route when watching content. Plus, I find VUDU to be extremely inconsistent and buggy. That, again, may have been the display. I certainly think there will be greater differences in the future as the displays reach higher peak brightness and higher Rec 2020 color volume. The issue is more to which of the two will win the war before that happens. That being said, when I switched out the displays, the x900e did not have compatibility with Dolby Vision, but I wasn't too concerned with it. At least not for the next few years.

Here's an interesting test performed by HDTVTest on Youtube. Even with the differences he's noting, I feel as though much wouldn't be noticeable had the TVs not been side by side. Certainly nowhere near as noticeable as the jump from SDR to HDR.

At times I feel like both HDR10 and DV tend to have in common colors that appear slightly over saturated to my eyes. Even at default color 50 certain things look too saturated and unrealistic. I tend to set color at 40 as of recently because of that

Since no Samsung's currently supports Dolby Vision, its impossible to use it in a valid test.

That is right. HDR10 is a minimum of 1000 nits. The LG's are not even close to that... most hitting from 450 to 750 so they need DV. Not a big deal... it's great that the LG has a way to get the HDR that it needs.

[RockyIII]

On oled tv the difference is negligible. Not worth stressing which titles are in DV and which are not

[jibucha]

'highly misleading' (irresponsible)
'that's not even close to true'
(i have a LG OLED55C7P)
"the difference is significant"

It's not the minimum it's the max for the 1000nit profile, just like the 4000, and 10000 nit profile, the content can be substantially less than the profile, there are some discs that are barely 300nits.

Also of interest is:
MaxFall

Average *Light*Level*not*to*exceed*400*nits.*The*Maximum*F rame Average*Light*Level*corresponds*to*the*highest*fra me average*brightness*per frame*in*the*entire*stream.

MaxCCL

The *Maximum *Content *Light *Level *(MaxCLL) *is *an *additional *Static*Metadata item*that applies to HDR Content only. Maximum Content *Light Level corresponds to the brightest pixel in the entire stream. *

Obliviously it's better to have a brighter panel, since it's closer to the mastering panel.

not a fan of Dolby Vision (i simply appreciate picture quality, which currently Dolby Vision is the best that i have encountered) - rightly and more accurately,

the comparisons that i regularly do, involve (Dolby Vision/UHD - HDR10/UHD - SDR/HD) content; mostly on the LG OLED55C7P using three players (one Sony UBP-X800 - and, two LG UP970's; one with Dolby Vision and one with HDR10)

additionally, using two players (LG & Sony) in SDR/HD on an HD display using both the HD/UHD discs, relating the results to what was encountered on the UHD display

so, i do compare Dolby Vision/UHD and SDR/HD (regularly); although also HDR10/UHD (as i originally communicated in my first post)

why? :: learning the differences (primarily), although most importantly, given the obvious picture quality (in all respects - not focusing hardly at all on HDR, which actually bores me), that i can decide how to manage my extensive library of content, and determine how to proceed in our evolving/improving picture quality developments

meaning that - - - currently my options regarding acquiring content in Dolby Vision are limited - - - and, my rather serious discontent with HDR10/UHD content - - - that, i 'was hopeful' that selling my open HDR10/UHD discs and simply continuing using what SDR/HD content i have and only acquiring Dolby Vision/UHD - - - this, did not work out so well, as my current leanings (heavily) after several rounds of comparisons, is to sell as many of my SDR/HD content as i can and to limit my future purchases to HDR/UHD content

this means that i will have to change settings on my display/player, for each disc/content (HDR10/UHD) as the 'other factors' of (resolution - 10-bit/12-bit encoding - color & contrast - etc) compel me to be even more disappointed with SDR/HD more than i am with HDR10/UHD, as i find viewing experience loses 'disappointing' to the point of not wishing to continue supporting that format any longer, unless of course, the content in 'poor quality' is a better option than 'not at all' which is why i still have a select few SDR/DVD content titles around - - - although i can see the time coming rapidly, that i will no longer tolerate 'non-picture quality' viewing experiences

oddly, my current perspective is that all of the improvements that UHD represents are important and appreciated by myself - - - that if HDR were not part of this standard; that i would not miss it - - - now Dolby Vision; that's an entirely different matter

for what it's worth, when i watch content in Dolby Vision, i simply enjoy the content without focusing on all this nonsense - - - it simply looks natural and realistic, only drawing attention to itself when it's absent

Bottom line is, if I spin a DVD but tell you it's bluray you will immediate be able to tell.
But if I play a 4K HDR10 and tell you it's Dolby Vision chances are you won't be able to tell

Justice League rocked!

[jibucha]

i entirely disagree :: if anything, the OLED has 'too much available light' which is why i am compelled to 'turn it down', which does not affect my appreciation of HDR (light levels) - and, i have 'seen' a 10,000-nits display, so i am well-aware of what HDR lighting is at it's highest level of performance

dynamic metadata is simply 'the tool' of managing images, which is not limited to 'high dynamic range' as it seems that most imply

Dolby Vision, specifically, affects all displays equally, optimizing 'all that are not as the Pulsar' (4,000-nits), that 'each' is 'presenting the best image quality that their respective design/manufacturer is capable of' - - - which has absolutely nothing to do with 'underpowered light output' or 'HDR10', which is 'highly misleading and inaccurate'

So if I played a title in hdr10 but told you it was Dolby Vision you would be able to tell like you can tell bluray from DVD? Sure...
