At about 8' distance from my 65" 4K TV I don't notice the difference between 720p and 1080p. At 5' distance I do notice. Even at 5', though, the visible difference between 1080p vs. 4k is tiny. And it's practically impossible to sit much closer than that and still have room to walk between the TV and front row. Maybe if I ever get a projector with an 80" diagonal screen or something, it will matter. My screen does HDR but it's not oled so the benefit to hdr sources is barely noticeable, and anyway you can get high-quality 1080p downsample rips that retain the hdr data.
