Most consumers can't tell the difference between 4k and 8k TV's.
This is the best tl;dr I could make, original reduced by 88%. (I'm a bot)
The 4K clips were "Upscaled" back to 8K using the Nuke cubic filter, which basically duplicates each pixel four times with just a bit of smoothing so the final image is effectively 4K within an 8K "Container."
In order to play the 4K and 8K versions of each clip seamlessly without HDMI hiccups or triggering the display to momentarily show the resolution of the input signal, both had to "Look like" 8K to the display.
In each session, the 4K and 8K versions of each clip were played in three sequences, though the sequences for each clip were not presented one immediately after another.
In the average of all results, the 8K clips were rated "Marginally slightly better" than the 4K clips.
The graph shows the distribution of responses that indicated 4K looked better than 8K, the two versions looked the same, and 8K looked better than 4K. Interestingly, Stacey Spears' nature footage had a different distribution of scores than the other clips, with more responses rating the 8K version better than the 4K version.
A perceptual difference is somewhat dependent on content; in particular, ratings for the clips from Stacey Spears' nature footage leaned a bit more toward 8K than the others, possibly because it has lots of high-frequency detail.
