Not so. All you have to do is hit the defined points in CIE diagram. The
Pioneer plasma sets hit them dead-on.

Indeed. None of the major display techologies deliver full spectrum,
nor do they need to.

This is true only if you have custom LUTs or decoding algorithms for a
display based on the relationship between the spectra of the lighting
and the CIE standard observer functions that cameras are generally
aligned to approximate. The other thing that no one mentions is that
trying to make up for spectral shortcomings with different filters and
decoding reduces the efficiency of the lighting system.

Of course.

There is usually a "rest of the story" beyond the naive assumptions that
get thrown around about reproducing color. This thread is full of
examples.

Those of us who take colour reproduction seriously use colourimeters to
calibrate the screen & display card LUTs.
