AMD H.265 destroys AV1 in OBS ???

I have tested video quality at the same bitrate 10000kbps, 2560x1080 (RX 7800 XT) in (OBS 20.2.3) AMD HW AV1 vs AMD HW H.265 (HEVC)

For some reason H.265 has better image quality, better detalization and more clear image overall even at higher bitrates like 50000kbps.
I tested it in many games H.265 always wins slightly or even significantly in some areas like s.t.a.l.k.e.r. shadow of chernobyl where difference is clearly visible with naked eye.

I'm really confused because a year ago when I had a RX 7900 XT I tested AV1 and it was better than H.265 at the same bitrate so what's going on there ? Or i'm wrong and H.265 always has been better than AV1 when recording gameplay with Radeon RDNA3 gpu ? Please share your thoughts and experiences on AV1 vs H.265 in terms of image quality at the same bitrate.

RX 7900 XT, XTX, RX 7800 XT, RX 7700 XT users do you have the same poor AV1 video quality results ? On paper AV1 should be better than H.265 but i remember with RX 7900 XT it was like that one year or so ago.
