Not saying this is accurate or ideal, just what I have been using (2017 LG 65 OLED B6).
GT Sport settings:
Exposure 1.0 EV
Saturation 100
HDR Peak Brightness 5
(You could bump up exposure if you find things dark, I would do that rather than change the brightness setting below).
LG Settings:
Eye comfort mode OFF
HDR Game User
OLED Light 100
Contrast 100
Brightness 50
Sharpness 10
Colour 60
Colour temperature C10
(I think the most important here would be brightness, you could maybe go up 1-2 points depending on room lighting and preference, just dont overcook it. The other is colour temperature. I prefer a cooler, blueish hue that tones down reds so use C10 in many games. Horizon Zero Dawn comes to mind as one that is overly red saturated on the LG with a warmer temperature).
Dynamic conntrast OFF
Dynamic colour OFF
Prefered Colour (all 0)
Colour gamut NORMAL
Gamma MEDIUM
Noise reduction OFF
MPEG noise reduction OFF
Black level LOW
Real cinema OFF
Motion eye care OFF
TruMotion OFF
Everything else at default value/setting.
(The black level low is a contentious one, apparently, depending on the HDR implementation of the game. You can get crushed blacks depending on how you have other settings, but this seems to work OK for the LG).
Hope that helps - I might play with settings at some point and see if I can suggest anything else!
Ok. Thankyou for sharing your settings with me. I'll try them out. Here is what i have been using. I didn't set the in game exposure higher as i find when you take photos the photo ends up looking darker once you take it. But there is probably a way to fix this.
I didn't like the default in game saturation setting too high because on the tracks, the green grass and trees looked unrealistic and cartoon like. So i have 70 which is max i can go. I like more lighter natural looking colours when it comes to trees and grass.
So i set the preferred colours for skin, grass, sky. With the dynamic settings for contrast and colour on high, the colours of the trees and grass still look more natural but with the dynamic HDR pop that makes them look real. Nurb looks amazing with these settings.
I have been trying to make the car paints look more like the real life accurate colours. I messed with the colour tint but have now set it back to G0, it was at G15. This seems to change the tone of the red greens and blues. I can't decide whether this helps make the colours more accurate or not really.
I have black level at high for brighter look but i know it could introduce black crush. Don't know whether really need super resolution on but it is. My colour temp is in between warm and cold on C5 not far below your C10 setting.
Dynamic Contrast, Dynamic Colour are set to high but every thing really pops with this setting especially when racing on the track. I don't know if the car colours will look more or less accurate with these settings on or off.
