Well the OLED TV would give the best PQ possible if that’s what you’re looking for and it’s compatible with all modes. The only downside to an OLED is that they can suffer from burn in if they’re used at really high brightness to play the same content day in day out. If you’re spending that much anyway then I’d go with an LG B8 or C8. I’m assuming you’re not going to max out the brightness and play the same game every single day for a crazy amount of hours for weeks on end anyway.
You can get high end LED sets that use good local dimming, which you would also get for that price. I’m pretty sure the Samsung QLED sets are supposed to be good, though I’d rather confirm it works with all modes first since that’s what you’re after.
