IMO 75" is where you start to get cinema experience. 82-85" are nice but that jump from 65" to 75" is big, for me. Given a basic 75" 4k with Amazon/Netflix etc comes in landed, delivered at less than $1k, IMO there is pressure for the mid range to get better. More zones, better contrast, better audio. I have a projector, and while its nice, its isn't the same experience, convenience as a TV. For sport, or a movie, maybe, for outside, definitely.
