Well, I tried and I feel I got the image to be a bit better and lessened the the yellow splotch look. Couldn't of course do it and keep things in line so yellow will read out like jhughy's run. To me it is a far better tradeoff than having this people look like they have jaundice. yellow areas on skin are still more pronounced than they should be.
I got greyscale dialed in and actually had brightness at 120 cd/m2 on white but to do that either required setting contrast high (which throws out colours and makes the yellow worse) or upping the backlight to +11 which then made the clouding far more visible so I decided to just give up the brightness target.
I used the 10 point controls again (sorry antala) because that's the best way to get the greyscale to be consistent and I was targeting a BT.1886 gamma curve which because of the mediocre black means the overall gamma is around 2.2.
av mode: movie
contrast +23 (if the cms actually worked how it should and had a functioning luminance adjustment then one could jack up contrast a good bit more)
resolution enhanced: off (this causes worsening of the yellow when it is on and it also dims the image)
motion enhancement: off (personal preference)
clear picture proc: off
cms hue (in order they appear)
-7, -5, -7, 5, -15, -1
cms saturation (in order they appear)
0, -10 (because yellow sucks so much), 5, 5, 5, 6
cms value: not used because this is broken and should probably be for the cms luminance funny since a luminance control would probably go a long way to fixing the colour issues on this model
colour temp 10 point setting on:
pos 1: 0, 8, -30
pos 2: -9, 9, -30
pos 3: 4, 17, -30
pos 4: 8, 16, -30
pos 5: 3, 18, -30
pos 6: -1, 21, -30
pos 7: -6, 18, -30
pos 8: -7, 21, -30
pos 9: -8, 17, -30
pos 10: 0, 0, -30
gee look at that, -30 for every blue value. stunned!
active contrast: off
film mode: off (personal pref)
digital noise reduction: off
colour gamut: standard
Watching some Person of Interest on blu-ray right now and I can say I'm not disgusted by the yellowing of some facial areas like I was before. Skin tones are still off yet this is passable.
