Dolby Vision is significantly altering colors. Why?

This is a pretty good video from the infamous Vincent. I recommend watching it all the way through. As there are many examples and some are more drastic than others. And in real life versus YouTube video, at least on my own setup (Panasonic UB9000 and LG OLED), the color difference is even more pronounced between Dolby Vision and HDR10. All other settings and white balance being identical on the TV.

In gist, Dolby Vision is turning most blues towards shades of green and most reds towards orange. It’s also removing red tones from faces, making them appear more monotone (brown/sepia) and less saturated and just plain wrong, IMO.

While many may prefer this muted look as more accurate, it would still be good to know why exactly is Dolby Vision messing with our white balance? I’m interested to learn what exactly is going on here.

i just don't like dolby labs they're "vision of colour . it's lousy on "midway" picture freezes up with pixels while sound plays for few more seconds then totally freezes . (got switch the dolby vision off) use the hdr10 .
dolby labs vision is like snake oil to picture quality . didn't have this hassle with DVD , Laserdisc or VHS .

I just bought the Sony UBP X800M2 to replace the first iteration which did not offer Dolby Vision (intending to move the older one to the den TV which doesn’t have DV capabilities). Am I going to be disappointed and experience heretofore unknown glitches in playback, or find the experience of color shifts off putting and looking manipulated? My version one of the Sony has pretty much played flawlessly for 2+ years, hung up only a couple of times early on where I had to unplug it to get it rebooted. Changed out the power supply to one more robust and nary a problem since. Guess I could just leave the DV off if it looks wonky, but changing out players then seems superfluous.

IMO Dolby Vision was created to accommodate OLED. OLED emits too little light for general viewing. Hence OLED = Improper. So OLED-ites now brand HDR10 designed for proper displays as "improper" to muddle that their OLED displays are the real improper displays that need improper Dolby Vision to muddle their performance to pretend to be as good as HDR10 on proper displays. Have I confused you as much I have me?

Careful folks, not to step into the bullshit.

LOL, yes but in the convoluted logic, I can certainly appreciate that’s possibly the workaround they came up with to extrapolate perceived nits when picture elements were perceived as too dim compared to LED displays. I have a late in the run Sony Z9D 65-inch. Supposedly it was updated with DV in a firmware update if it hadn’t already been factory added, but will have to confirm that. Possibly looking to switch this one out to the den as well (a 1080p set from Panasonic which still looks terrific but being 9 years old obviously isn’t UHD, though 4K discs look fine when played on the Samsung UHD player connected). Anyway, guess the only thing to do is give the M2 a whirl and see what it looks like. Thanks for the input.

Too late and it’s smeared up the walls.

Not trying to encourage the spreading of excremental comments, but I did switch out the older X-800 for the M2 to try the Dolby Vision option. Initial viewing was Total Recall (1990), which I figured was a good candidate due to the sometimes lurid color scheme and variety of background effects and Mars landscape, etc. After watching the film with DV activated, I went back to sample scenes and compare. I couldn’t figure out a way to quick switch between activated and disabled, which would make comparison easier, but I must say I did think the DV presentation was a bit smoother and had subtleties which enhanced the picture quality. That may not hold true for other transfers of things in the queue to watch, but though the differences weren’t such I’d have noticed anything amiss in the absence of a comparison (trying to be objective and fair), I’m at least glad to have the option to watch DV-encoded discs.

Oled emits too little light for general viewing... Are you feeling alright?

[uncledougie]

LOL yes, luckily my beloved set is the Sony Z9D, which occasionally evokes in me a squint when there’s an abrupt changeover from very dark to a bright scene. The only part of Total Recall that seemed too dark and a bit indistinct were the opening credits, but that was viewing with both DV engaged and not, so it’s inherent to the source.

Well Jimbo your link is broken. But I suspect it's one of Vincent's older videos and I've probably seen it before.

DV is a cool little nugget of tech in theory but in practice Dolby is too lax with manufacturers and streaming services-- letting them pick and choose what "works for them" regarding implementation. As long as they get their licensing fees who cares right. 10 different "profiles", Dolby Dark and Dolby Bright, MEL vs. FEL and TV led vs, player led etc. They've turned it into a clownshow everyone is speaking about DV differently because unless we run the exact same gear and firmware we're likely all having a different experience. In general I like what I see from DV on MY setup but that's all I can speak on.

[uncledougie]

If I have to delve too deeply into the weeds for extracting that last little bit of picture nirvana, it suddenly becomes all about that, not the film in question. And no doubt each setup with any given title will vary and give different experiences, even with two people in the same room watching together, depending on personal tastes. I can want to maximize the experience but once I find an acceptable general confluence of brightness and clarity, I prefer a “set it and forget it,” and just proceed to a satisfying watch. At least now the setting options are a bit broader, which isn’t a bad thing. Thanks for your perspective.

Aside from the link, I think I saw the same Vincent video. I remember he or someone else did a comparison about Dolby Vision and what is outputting on the Panasonic Blu Ray player and the TV(newer OLED?) were different. In fact, I believe the Panasonic player was clipping at the very bright highlights IIRC.

This does seem to apply that even with two different devices using Dolby Vision, the tone mapping is not the same. This is sad, as it there is even less of a standard for HDR across devices that support it.

The DV is obviously much much greenier on whatever TV he's using there. But does he say that he's adjusted the white balance to match the calibrated HDR10 side? On some Sony TVs they've got a custom white point for DV which needs adjusting for, you can calibrate SDR and HDR10 using the exact same white balance settings because the TV transposes one to the other, but when using the same settings for DV it appears greenier, funnily enough.
