Don't make me show you the power of poor image compression. (Because that involves a bit of work in this heat.) It can make the gorgeous looking Horizon Zero Dawn like trash. People actually claimed that the game got a huge downgrade shortly before release. They were deducing that of a highly compressed video. What a surprise when the game was crisp and clear and beautiful on release.
Image compression also has nothing to do with resolution. A tiny little png image can have super clean and crisp image quality while a huge 4K image with compression looks like shit.
The alleged missing details, like the mentioned rope detail, are very likely just due to image compression. It's speculation at this point with only that terrible quality footage.
Also telling me about details is crazy. I am for years THE one in this forum and elsewhere who finds all the actual downgrades and missing details first. I think people already think I am kinda crazy and obsessed for that. I would know if there was a definite downgrade. I would tell you all before anyone else does.
