Right, but look at the U, V planes . It show more damage than up/down scaling only

4:2:0 => 4:2:2 => 4:2:0 . You would expect some blurring if they were not using nearest neighbor (aka point resize in avisynth) , so very small color details will be expected to be blurred. But you have compression artifacts on top as well. Encoding source bypasses that up/down scaling step

But it still looks like something additional is going on too
