The DCI-P3 Color Space looks really nice and vibrant, except that it makes pure white darker than other colors. Is this a quirk of this color space or a bug? Either way, coud it theoretically be fixed?
It looks very good in movies until a bright light source, like a flashlight or an explosion, shows up looking grey ...
I'm using a Q90R if that matters.
Hi, thank you for replying.
Yes it looks like this almost everywhere. Only way I found to get correct whites is using the Movie picture mode with contrast at 50 and the ST.2084 slider set to +1 (looking at this video https://youtu.be/lFbua14wDJE on the TV's YouTube app, pausing at 2:06)
The TV model code is QE75Q90RATXZT, running firmware 1356.2
Yes, it's a known problem with Auto Colour Space. White detail gets blown out to the grey you are seeing. Posterization can also be seen in some instances. It's really obvious on the Planet Earth II Intro as the logo appears (around 2.15 on EP 1); look how the highlights on the left edge of the earth appear different between Auto and Native. I find Auto overly saturated on DCI-P3 anyway,so just use Native.

Did a few more tests on my PC and I think the above only works for HDR content.
Ah nope, I stand corrected.
Watching this video, white still looks dim on patch of light on the ceiling but not on the sun flare.
Left is Native colour space, right is DCI-P3, all other settings are identical, both are in HDR.
My original assumption was that less saturated colors get brightened less; but it could also possibly have to do with actual brightness. The sun flare here is brighter than the patch of light on the ceiling in both color spaces.
