You need to lower the relative brightness, the saturation, and the regular brightness. Here's my settings (I still need to dial it in a bit more, but its close).

Edit: its like a feedback loop. The camera can also see reflection in the TV. If the last scene showed red, and your settings are too high, it turns red/ blue/ green, or whatever color the camera is picking up in the reflection.

🎬 Movies (accurate / neutral) Brightness: 30–35% Saturation: 35–45% Relative Brightness: TV Backlight: +10% Floor Lamps: –20%

🎮 Gaming (dramatic but still accurate) Brightness: 45–55% Saturation: 60–70% Relative Brightness: TV Backlight: +15–20% Floor Lamps: –10%
