First image is the 4KUHD, clearly showing showing contouring/banding inside the diffused light gradient area on the left.
Second image 1080p Blu-ray which does not suffer from the same issue.
[EDIT] Resolved: See this comment
Just curious, why would I keep/remove the default tweaks for H265 MKV 2160p60 4K preset:
>strong-intra-smoothing=0:rect=0:aq-mode=1:rd=4:psy-rd=0.75:psy-rdoq=4.0:rdoq-level=1:rskip=2
I realised that removing rskip=2 and/or rect=0 (please confirm?) more than doubles the encode speed on Slow preset.
I'm not sure what the other parameters do – could someone tell me, based on their experience or using or removing them? Thank you.
Why can't I encode an MKV to match the same colours as the original source?

No extra bloom or contrast; colours are rich and standard HDR-looking.
[Encode 1 - Colorspace: Off]:
Results: contrast seems too high with added bloom effect.
[Encode 2 - Colorspace: BT.2020]:
Results: Colours look faded/washed out
