open with ms paint and view in full-screen, see the distance you need to see the individual lines. for me on my 49" 3840 by 2160 tv its about 32" away for the horizontal and vertical to be seen.
"At IFA 2019, LG made clear that it didn't think Samsung's 8K TVs
conformed to a true 8K spec, even though it had the correct number of
pixels, according to Forbes
It believes that Samsung's QLED pixels are not clearly distinguishable
from one another, so the effective resolution is lower than 8K.
Naturally, it thinks its own 88Z9 OLED
and LM99 LCD TVs are sharper and do meet a true 8K standard."
so there is a problem with resolution with the qled, its pretty its very beautiful but the resolution is a bit poor. at least for distinguishing 1 pixel lines 1 pixel apart. so if you own a tv that allows the resolution to be the actual resolution, see the lg comment, then you might be able to sit farther away and distinguish the image.
i will upload the videos now in a 7zip folder, open the picture in ms paint, choose full screen, to see the image. you might need to use virtual desktop if you look at the images in vr.
me when i saw the qled results;
and you can't open the 16k file with ms paint, not to amplify negativity, its stealthy;
