That is true, but it will only work effectively if the display 
hardware offers enough bits of color resolution, and if the display 
hardware supports updating its LUT, or if it is possible to provide 
many more than 8 bits of color resolution (e.g. 12 or 14 bits) to the 
display.  In order to be cost effective, the display should be built 
with the correct color primaries in the first place.  Color primaries 
are baked into the hardware.

I have yet to see any of these cell phone display reviews do an 
evaluation of the effective bits of color resolution.  Everyone is 
looking at contrast levels, screen reflectivity, and color primaries.
