Cyan is severely under-represented by monitors, so the extra pixel is a dedicated cyan. It dramatically improves the ability to display blue/green colours.

I was under the impression that yellow was a better candidate for this. But whatever. Can hardly wait for RGBCYM televisions that will make my wallet bleed.

		The chromaticity diagram is basically a straight line between 640nm (red) and 545nm (green), so anything in between (including pure yellow around 570nm) can be reproduced with a linear combination of red and green. RGBY televisions do exist, but their goal is to boost brightness in the yellow region, not color gamut.
