Is that why DV's brightness is significantly reduced - according to both my eyes and my colourimeter - compared to HDR10 on the ZD9? That because it's requesting too high a nit level for what the TV can do the output is being dimmed down too aggressively? Or was the LG EDID even dimmer? Sadly it looks as if the problems with the LL mode are not just on Dolby but on Sony too and I don't hold out much hope that both will be corrected.

Stacey- you seem to be the only person in the world thatís understands HDR/DV. I just upgraded to a LG C8 and bought the Sony UbX 700. Everything is running through my Denon 7200wa including my Apple TV 4K. DV passes through at RGB 8 bit for the Sony 700 and ATV in DV.

HDR 10 passes through in BT2020 10 bit for ATV and BT2020 12 bit for Sony 700.

Iím used to seeing BT2020 10 bit from my days with Samsung JS9500 and 8500 uhd player.

The settings that are passing through seem correct from statements Iíve read the past couple of days?

Also which blu Ray player is the best for chroma sampling for DV in your opinion? Thank you!

I would not use the LG EDID either as it is requesting a lower nit level for Dolby Vision, but Sony is requesting too high a nit level.

The 8-bit RGB for Dolby Vision is secretly 12-bit 4:2:2. This means you are in TV-led mode, which is good. Sounds like the ATV is working that way too.

So after, checking out your DV montage. I remembered a comment you made about the brightness having an affect on the sharpness, not a result of the display sharpness setting, or edge enhancement. This thought came to mind, is that partly related to the master being 12 bit, and what DV does with the encode?

I also read a PDF, on the importance of 12 bits or 4096 shades. I've come to realize, I never fully had a grasp on what 12 bit meant to the look of a HDR grade or particularly a DV one. You essentially get a significant boost in overall detail, dare I say, "fine detail".

There's something about the way DV combines the base layer and enhancement layer that has yet to be fully understood.

The montage is the representation of how HDR gives the impression that you are looking through a window or actually there. Great work.

Ditto on don't touch contrast, but I discovered my display, in the mid tones was way under luminance. So right now, Gain is the only part of grayscale I have calibrated. Over time brightness goes up and cloud detail becomes even more pronounced.

If you go to the butterfly montage and pause on the Ferris Wheel shot, you will see what I mean. The perceived sharpness improvement is from the contrast improvement of HDR.

Bitdepth will help with gradations, not sharpness.
