LG C8 Settings.

In response to a question in the Member's Kit Pics section:

For simplicity's sake, use the Cinema preset for all picture mode:

From the initial PICTURE screen:

Aspect Ratio - Original
Energy Saving - Off
Additional Settings: Eye Comfort Mode - Off
OLED Panel Settings - Screen Shift - Off
Logo Luminance Adjustment - Off

Picture Mode Settings
(SDR / HDR10 / DV):

OLED Light - 25-40 / 100 / 50
Contrast - 85 / 100 /100
Brightness - 50
Sharpness - 0
Color - 50
Tint - 0

Expert Controls:
Dynamic Contrast - Off
Super Resolution - Off
Color Gamut - Auto / Not Applicable
Color Filter - Off
Gamma - 2.4 / Not Applicable
White Balance
Color Temperature - Warm 2

Picture Options:
Noise Reduction - Off
MPEG Noise Reduction - Off
Black Level - Low
Real Cinema - On
Motion Eye Care - Off
TruMotion - Off

These are the "purist" picture settings. There's some leeway on SDR OLED light depending on your in-room conditions, but between 25-40 you're within the correct ballpark SDR range. The technically correct Gamma for SDR is 2.4, but if your room is bright, feel free to change it to 2.2.
