They look nice. I got Sony A85 (A8H) oled from sale on december and it is really good for movies, series and gaming
While hdmi 2.1 features (VRR + 4k120) add some benefits, I would argue that they are kind of gimmicks on consoles.
VRR = most games are targeted to have locked 30/60 fps anyway, and few dropped frames here and there are nothing to care about
4k120 = 120Hz is useless gimmick that wastes limited resources, not many games will use it and 1080p/120Hz is smarter choise anyway if it means better visuals. But 4k/60 or 1080p/60 is more than enough for consoles. For PC I get the minor benefits.
eARC = useful, and 2020 Sony models have it
ALLM = Sony have their own implementation for PS5, which should switch between game - movie modes, and it is not a big hassle to do it manually anyway
Console games have been enjoyable for +40 years on TVs so these features arent essential.
Just saying if someone sees 2020 TV on good sale and it doesnt have hdmi 2.1 = I would not pay hundreds more for those features, if 2020 model is 1000€ and 2021 model is 1600€, it's not worth it. If prices are almost the same = then I would pay the extra for new XR + panel upgrades
