It would be interesting to plot all of the achievable colors of this LED on the chromaticity diagram. Presumably it'd be some sort of circle/ellipse around white but might have some dropouts in certain parts of the spectrum?
Pure wavelengths are on the horseshoe-shaped outline of the CIE 1931 space. The straight line connecting the ends of the horseshoe is the line of purples, which also isn't monochromatic.
Presumably they wouldn't need to do a pixel-to-pixel mapping, but could account for the wavelengths of neighbouring pixels to produce a more faithful colour reproduction at an effectively lower resolution.
