I've got a 55" 4K at a viewing distance of maybe 6', tops, if you're leaning waaaaay back on the couch, and can only barely tell the difference. A good 1080p source (high bitrate h264 or h265, or a normal ol' 1080p bluray) looks a hell of a lot better than Netflix's 4k. HDR matters a ton more than 4k itself does, as far as how good something looks.

[EDIT] and what really matters is having semi-decent speakers in a somewhat-OK 5.1 layout, with a proper receiver. I'd drop to 720p on the picture before I'd give that up.
