Black levels issue on Quest 1 OLED display

[fakedeltatime]

Description

The colors, especially black, on the Oculus Quest 1 seem to be somewhat off, with the biggest issue being that black is gray. This happens in game environments, as well as when the stream is not enabled but the streamer is connected (when having the black screen issue for example).

General Troubleshooting

• I carefully followed the instructions in the README and successfully completed the setup wizard
• I read the ALVR GitHub Wiki

Alvr has color settings, you might want to adjust those

I forgot to mention in the original post that I did give the color correction settings a try, but to no avail.

Even setting brightness to minimum, which also resulted in a (visually) completely black display, rendered a shade of gray in the headset. The ALVR native blank environment with connection instructions has properly black elements.

That's probably on the display then, it can't properly present black

Could you explain this further

No, the display can present black properly (with clearly turned off pixels), since it is OLED, as it does in standalone content (such as the ALVR headset client)

Could you explain this further

I mean that the dark grid environment that the headset client of ALVR opens has perfect blacks, where as the stream does not. Going from the native black levels to the non-black blacks of the streamed content is jarring.

Can confirm I have the same issue. Running KDE neon, in Half Life Alyx, around chapter 3 ish where it is dark, it looks like I am using an LCD headset. Very grey rather than black.
