HDMI IN1 to IN4:

Amp has zero setup parameters for deep color or anything similar. Cables test ok, hdr and resolution are ok, Oled has deep color enabled, the 8bit banding is the only problem.
When you write "works fine when i bypass the AVR" do you mean physically removing the AVR from the chain? Many AVR's have a "bypass" or "direct" mode for the video portion of the HDMI signal. That is usually the preferred method of using an AVR because it eliminates (or at least greatly reduces) the possibility of something in the AVR from distorting the video signal.
