This is our calibration settings for the LG OLED EF9500 4k TV. Copying these picture settings should be a good start for your tv.
'Expert1' picture mode has very good preset for everything, including gaming. The 'Game' picture mode doesn't have a lower input lag, but make sure you disable 'TruMotion' otherwise the input lag is quite high.
If you find the picture too dim, increase 'OLED LIGHT', not 'Brightness'.
For DVDs or SD channels, turn on the noise reduction features.
You can get a slightly wider color gamut when 'Color Gamut' is set to wide, but this isn't recommended for normal content because the colors will be over saturated.
The rest of the screenshots below show our 2pts, 20pts and colorspace calibration. We really don't recommend you copy them on your TV. It varies a lot per unit, especially on OLED TVs. Try them if you want, but if you notice any color banding, reset them.
