I'm no expert.
All i can say is do not waste your money on high end tv's ($5'000+) when all the feeds are terrible.
It's like having a ferrari, but no quality fuel to feed the engine with.
1080p looks good on blu ray, nothing else.
What I am trying to say, is do not waste your money on really expensive tv's (4k or Oled) because Comcast, Apple tv, and Netflix, simply are not good enough to give an excellent picture.
In times of High traffic, Netflix drops to 480 p sometimes.
Although expensive tv's do an mazing job at upscaling (Sony, Samsung 4k + Oppo BD player), there's nothing they can achieve if we continue to feed them with a carp signal.
A normal antenna looks so much better than Comcast, Apple or Netflix...
