I did not say perceivable colours but displayable colours.

Lets take a hypothetical blue car under controlled day lighting and
photograph it, then display it in the very best of monitors (with any
necessary adjustment if you prefer), how many colours does the image on such
screen display? Lets take a blue card, a yellow card and a red card, place
them on a white background, again in a controlled lighting situation,
photograph them, download such image in your super computer with super
screen. How many colours do you perceive? How many colours do you perceive
or able to count count in a typical black and white photograph? I am sure if
you carryout this basic experiments it will become clear to you whether the
world is that multi-chromatic, and most importantly whether you actually
need all that extra gamut the cinema display offers if not for your "luxury"
or if this is very harsh then your "choice".

Oh, I should add that if your "GameBoy" displays such colours that you are
pleased with, and you can reproduce them in a printing device what's wrong
with that?
