If you own a 50" 2160p ("4K") TV and are sitting more than 1.8m / 6ft away, you're already at the edge of being able to perceive any resolution increase over 1080p. For a 65" TV, its about 2.5m / 8ft.
So no, at typical viewing distance you are very unlikely to notice a sharpness decrease.
Tangentially related, but this is also why the 4K chase on this console generation is so stupid. The vast, vast majority of people will be viewing their TV way beyond the recommended viewing distance, and thus will only be resolving to 1080p with their eyes. We should be chasing better-looking effects and 120 FPS.
I’m at 65” and less than 2m away, and I absolutely can tell when text is not rendered at native resolution, which is why I’m also confident I’d be able to notice the matte coating too.
(I am also probably like three standard deviations _more annoyed_ by the blurriness than an average person, I’m more than willing to believe that an average person wouldn’t be able to tell, or at least wouldn’t be bothered by it anywhere close to the degree that I am.)
