Yep - observer metamerism can be an issue in practice, especially noticable
when more than one person is viewing something. It applies to instrument matches
too though - an instrument may be perfectly calibrated against the standard,
yet a perfect instrument match may look like a mismatch to you, because your
eye's color matching curves are different from the standard!
