This is precisely what all of the high end wide gamut display models,
be they from NEC, Eizo, Samsung etc., do to "emulate" different
gamuts. There is a programmable color processor that internally maps
the input video into a different and smaller output gamut. It is
effectively mixing colors to desaturate and alter the hue. The
processor is not normally a full 3D LUT, so there are tradeoffs in
doing this and it really is just an "emulation".
This feature is useful with wide gamut displays if you are working in
a non-color managed application and want to emulate a smaller color
gamut such as sRGB or AdobeRGB.
If you want to measure the true gamut and spectrums of the primaries
you need to switch the monitor into it's native color gamut mode.

I, along with a few other people, believe that these new Samsung XL LCD LED
monitors have the capability of "managed gamuts", that is, through an astute
tuning of the individual RGB LEDs, they have the ability of producing
primaries with specific chromaticities. This would not be a LUT trick but an
advanced hardware capability.
