The guy has 1 post and made it like year and a half ago, so don't expect an answer.

But as for the 3, it's most likely how the upscaling algorithm/AI processed the original texture. Those AI's we use for upscaling aren't real "intelligence", they lack imagination and foresight, they can't see the bigger picture and while sometimes the result of their work is great, sometimes it's just ugly when they add details to artifacts or blend things that should have high contrast usually when the source image was really low quality.
