My viewing position is about 330cm/11ft from the wall where my tv is mounted. That works out to roughly 80” television for 4K viewing pleasure. https://www.rtings.com/tv/reviews/by-size/size-to-distance-relationship
8k would be ridiculous, and the compression would be a significant factor.
Remember when ISP companies went after people who used over 500GB in a month? I remember.
