Again, while it is true that you can make any color within a given gamut
with some combination of R,G, & B, it is NOT true that you will get the
CORRECT color for ALL colors if the decoding matrix is not correct (very
common in many consumer sets over the years, if the gamut is wrong, if the
gray scale is wrong, or if the spectrum is wrong. To get the right mix of
colors for all colors in a given system, you have to play by the rules for
that system. If you change them, such as is the case when you deviate in
spectral response from the CIE curves, you have to make it up somewhere
else. This gets very complicated and is precisely why some people who are
sensitive to color reproduction have noticed that LED based displays have
had trouble with some colors.

I think that the important point is that the CIE standards are a subset
of colors, not the millions of colors people think they are getting from
a computer display.
