Screen size is a matter of how far you sit obviously. ~32" and under are usually monitors so ~2-3 feet. 48 inch are personal tvs and 55" + are for living rooms.Just the fact you ignore how close you sit in your chart already tells me you have no idea about what you talking about. Educate yourself before posting nonsense.
But as always the people most obsessed with simple metrics aren't usually the brightest and ethomaz agreeing with you is all the proof I need.
The percentage it takes from your FoV is all that should matter. That's why 8K makes sense for VR but doesn't make sense for the vast majority of flat screens and set ups. Depending on how close you sit from your TV a 40" TV can take the same percentage of your vision as 65" screen seen from a little further away.
Most digital movie theater screens to this day aren't even 4K and I don't see people complaining that they went to watch a movie in a digital screen and it sucked. Even many screens advertised as IMAX are just 2K.
Yes most people are ok with poor performance. Cope or rope.
