Sure, you can go spend $2,500+ for a high end 60", but the real difference is really small.
Is it? Not much point getting one without good HDR capabilities as that's where you'll find the benefits for a game console. (It might be native 4k, textures and environmental detail still aren't up to 1080p capabilities) $600 will get you the resolution, what about the 10 bit wide color gamut and HDR?
