Not only that, but your monster CRT probably doesn't match a smaller
CRT; and an old-ish CRT whose phosphors have aged (and whose focus
may have gotten a bit fuzzy) probably doesn't match a new, sharp
one.  Different LCDs may not match each other either, esp. if they
use different backlight technologies or if some of the backlights
-- or faceplates -- are subject to color shifts with age.

and there's more involved than physics and optics anyway, e.g. the
neuropsychology of human visual perception.
