low bandwith remote desktop quest 3, rtx 3090, unexpected bad picture quality

[CryptoAsc]

Sunlight + Moonlight look perfect even at low bitrates. Quest 3 + tailscale/zerotier.

I think I tried all possible settings in ALVR but it just looks like some1 shit on my screen compared to moonlight/artemis at 20-30mbit. I suspect the encoder is optimized for higher bitrates or I am missing something absolutly basic. I couldn't test high bitrates cause im not visiting the location of my pc soon.

I sadly miss the vocabulary to describe the issue, some parts of the picture look good some are like foggy, idk if this is color banding? I also added uniform black/green vr background to reduce needed data didn't help, i feel bitrate should be sufficent. h264 and h265 look like they have the same issue. cant test av1.
