Digital camo officially called multi-scale camouflage, pattern that breaks the contour on small distances and on medium, because pattern is complex and looks different on different distances.
But it doesn't really matter, if there are pixels with square shape or classic pattern, color distribution and sizes matter. Pixels have some small benefits in production (i.e. easier coloring), but overall it is just for cool look. Technically, small pixels make border between colors less noticeable on large distances and this helps to avoid detection on moving, but small circles will do same effect.
Camo on KrAZes on photo made pixelated for displaying purposes. It is 21st century etc.
