You can usually tell the difference by taking a different
point of view, or shifting the position of the light (which
amounts to much the same thing), and comparing the
results. (But that's difficult if you insist that your
present POV and lighting are The Best.)

It matters if and when it makes a difference to us, not
otherwise.
