If you going to game on it lower the oled light to say 40/50 I have mine at 50, that way I don't need to wear my sunglasses, also don't display any icons on desktop or wallpaper leave it Black screen and hide the taskbar but if you watching HDR content just leave it at default and put Logo Luminance Adjustment = high, to prevent a burn -in, you must mix your content not always uses the same game on it with allots of static UI on screen then you be fine.
LG OLED TVs come with special features and settings to preserve image quality and prevent burn in and image retention. First, there is a Screen Saver feature that will turn on automatically if the TV detects that a static image is displayed on screen after approximately two minutes. There are also three options (available in Menu setting > Picture settings > OLED panel settings) that can be used to preserve image quality. The first of these is the Clear Panel Noise feature that preserves the quality of the image on the display panel by resetting the TV so that it clears the pixels. This feature can be turned on when needed within the settings mentioned above. The second feature that can be employed is the Screen Shift feature which, moves the screen slightly at regular intervals to preserve image quality. A third option is the Logo Luminance Adjustment, which can detect static logos on the screen and reduce brightness to help decrease permanent image retention.
Cheers for the details - great help!
