Depends on your setup. On my 100 inch projector screen you can immediately tell when it’s not 4k. And low bitrates (like Netflix) become especially noticable with rubber banding and loss of sharpness.
No I’m also talking about resolution too. You can tell on 100 inches. On 100 inches a 1080p pixel is more than one millimeter in diameter. You can definitely see that when you sit 3 meters away from the screen. 4k will give you visibly more sharpness. Provided of course that you don’t butcher your movie with terrible bitrate compression.
1080p is enough for most people’s eyes. What do you want?

Those are compression and bandwidth issues, not resolution.
