Discussions about this are very tedious, because people have hard time making distinction between "being able to see the difference between 1080/4k/8k content" and "being able to see the difference between 1080/4k/8k panels". I'm sure there's plenty of content (especially streaming content in mediocre bitrate) where people would be hard-pressed to tell the difference. But I think if people went back to 1080p _panels_; they'd actually rather quickly notice how much worse the text-rendering is, and that the UI looks off for them. Moving up to 8k would definitely be a smaller step-change in clarity than 1080p->4K and many people wouldn't feel it's worth spending extra; but I don't think it would be literally indistinguishable.
