Is say most people not being able to feel the difference between 1080 and 4K to be inaccurate. I'm always seeing people look at 4K video after watching 1080 content and remarking how crisper it is. Of course there is a very large majority of people where what they have is good enough. When the iPhone went retina people argued that the extra pixels won't make a difference. Then they tried it. Now look where we are.
