A blasphemy....I know....

Well, someone said 'total marketing bull*hit', that may be true of many things retail, but the 'color shading difference' sans marketing on this unit, calls for it to produce 256 colors plus one more factor of 256 making the total of shades, not in the millions, but into the >1Trillion color shades.
I, without knowing somehow fealt that the colors were more approximation and not the full range of color that is shown by sunlight or a halogen, and that is apparently true, if we're to believe that the shades of color reproduction have increased by such an order of magnitude.
I only know that there WERE more colors, and that sublte 'combinations' of others were rendered with more subtle shadings. My eyes, like my ears didn't lie to me.

First off, pigments are a completely different conversation than the RGB light spectrum.

The reason I say the extra yellow color is marketing bulls#t is because RBG are the primary colors of the entire spectrum of light that our eyes can see. You get every other color in the spectrum by mixing them together. When we see the color yellow, we're actually seeing a mixture of pure red and pure green. That's what yellow IS. They can't add and extra yellow color because it's still red and green mixed together.

The question is not whether three RGB lights with variable intensity and backlight can produce yellow. They obviously can. The question is whether or not adding a fourth light in the way Sharp does produces a better picture. The newest large-screen RBG LCD TVs look better than the first RPTVs which came out but it is still the same RBG. The goal is a better perceived picture, not satisfying purists' theoretic ideals.

Anyone who has ever painted knows that you can use the three basic colors and white to get to everything, but I have known any number of painters over the years and none of them starts a painting with only four tubes of paint in the box.

Typical logic had me believing that the additional yellow would produce an Enhanced RGB. Printing CMYK, whether on press or some digital output device is commonly augmented with special colors to enhance areas where the standard 4-colors go flat.

Generally, I see reflective color (printing/painting) as very lossy in color purity. Additive color (light) can exist in a much more loss-less environment. I have a lamp that use 4 halogen "guns", three are dichroic filtered to produce pure RGB and the fourth unfiltered White light. Each of the RGB and White can be individually intensity controlled. To cut to the chase, if I added a Yellow lamp to the RGB mix, the colors produced would be altered or pushed in a direction. I am assuming I could readjust the RGB mix to repeat the original color prior to the addition of yellow. So theoretically, I am not necessarily improving the color, just changing the hue.

In the case of RGBY in a matrix, I think the fields of color can be positively enhanced at the glass. The processing would be more complex to properly incorporate the yellow push, but the addition of a specialized color could theoretically improve the richness of hues.

I look forward to seeing RGBY.

So whats this do to HDMI? And will it carry full 1080P?
