My OLED light is set to 35, brightness 40 logo luminance = High contrast = 75 but I play in a dim room.
This is the main problem the user just turns off everything without knowing what it dose (logo luminance) It decreases the OLED light of the pixels when it detected a static logo preventing burn in
ABL only kicks in when you set the OLED at peak 80/100 lowering the OLED Light, and or Contrast to around 40 still stop ABL from kicking in.
LG's OLED TVs also dim when more than 60% of the picture is bright. (ABL) While this is unlikely to happen during normal video playback, it affects calibration (especially when using fullscreen patterns) and happens when the TV is used with a computer.
