ABM will reduce the backlight and compensate by adjusting brightness and contrast of the image. It has 5 levels: 0, 1, 2, 3, 4. 0 means off. 4 means maximum backlight reduction. IMO, 1 and 2 look okay. 3 and 4 can be quite impactful, both to power and visual fidelity.
I tried this with 6.9 and it looks weird with an OLED panel used with
dark UI settings.
The dark is no longer dark, everything is brighter.
I turned this feature off with amdgpu.abmlevel=0.

Would you mind filing a bug with the details please? This was something
that was actually explicitly checked against an OLED panel. ABM
shouldn't be applying to OLED today so this very likely points at a bug
somewhere in the stack.
