I did a quick 2-pass test and a CRF test encode and hevc-aq smoothed the flat background quite heavily in both cases. The bitrate rose quite a lot in CRF mode:

AQ-mode 1 : 4425 kbps
AQ-mode 2 : 4706 kbps
AQ-mode 3 : 5999 kbps
HEVC-AQ : 5094 kbps

I'm really not convinced that aq-mode 2 is a better option than mode 1. To me it seems to also smooth the flat areas too much and that becomes quite annoying once you start noticing the gradients that result from it. See the wall between the women.

Original frame before encoding:

AQ-mode 2:
