> There is a large difference between 1080p and 4k
I cannot tell the difference at normal viewing distances. Up close, sure.
This is how they get you to buy the 4K version, in the store you are standing 2 feet from the screen and you can see the pixels at 1080. Sitting at a normal viewing distance and 1080 looks great.
Actually large LCDs (>65") were pretty uncommon in 2010 but if you ever watched a 1080p DLP television I would be surprised if you didn't notice when looking at them side by side.
There is also of course the issue where people have bad internet (so netflix or whatever destroys the bit-rate, or they have the cheaper 1080p only plan... is that still a thing?) or old cable boxes plugged into 4k televisions.
There is a lot that people can do to inadvertently destroy their image quality without knowing which is not great.
Problem is I am not looking at TVs side by side. I'm watching a movie or a show, and the enjoyment I get at the correct viewing distance is unlikely to be significantly more on a 50" or smaller TV.
