I agree with you, most people don't realize the complexity of color
mixes create a color. Those CMYK and CcMmYK printers have a pretty tiny
pallet to start with, from which they need to make thousands of color.
Many people pull their hair out trying to find the cause of banding in
middle density colors, wondering why it only occurs there while all the
other colors seem have no, or very limited banding, for instance.
Quite often this problem is the black head. Many mid-density colors use
black to grey and deepen them, and if that black is not being
distributed evenly, subtle banding occurs. Printers using a lighter
black (gray) often find it even harder to diagnose.
