This isn’t image manipulation of the 1990s. You assume it’s set on isolated pixels with massive contrast. It’s calculated by neighbor to achieve the pattern.

This is just a result of inconsideration driving laziness that they’d crop to a median level of the graphic to cater to the skin with less reflection and reads light easier and then releasing it as ‘done’. Software is much more sophisticated than you’re giving credit. But It’s only being used to that potential in such industry as film.
