the 2020 LG Nano 90's are actually much improved this year IMO (better dimming algorithms and power control).
For off-angle non-OLED's there's also Samsung's Q80T & Q90T which have a similar filter to the Sony's.
Was looking at a 2019 65” SM9010, specs are good and decent reviews.
Have discounted the Samsung’s as no Dolby Vision.
Have looked also at the newer LG NanoCell, the 65” Nano86 and what you mention, the Nano90.
Probably down to these now....
