I'm not sure it's the parent's point (I suspect it is), but mine would be that it might be you get 80% of the "it's like they're there in the room" effect by having 8k; good lighting; well-separated, good quality, stereo sound; a purpose made space without distractions; etc.? If you've only had 480/720 on a small screen, with a mono microphone with poor lighting, lag, dropouts, then just fixing those things and making it 2k+ might be surprisingly good (ie will have an emotional impact due to the truer representation)?
