Here are the perceptual charts based on Genoas white paper. I posted here as it gives me a chance to add some review words to my charts - maybe making them more understandeable.krasmuzik GENOA
They first propose a Wide Gamut - the advantage here is that gamma is not changed because Cyan is a deeper towards Blue and thus you do not get brighter Whites - but Cyan gets an F---
The natural greyscale point defined by the RGBCY primaries is thus grossly blue - give it an F---
But that means Magenta is deeper towards Blue as well - give it a D-
Green is deeper and more Cyan - give it a D+
Blue and Yellow are just a bit overdone - give them a B. Red is overdone - give it a C (note many display like Sim2, Infocus SP7210, Optoma H79 are similar reds)
So if you were watching an HD source on this gamut - the picture would look very strange. Especially skies and grass - it would look like these SciFi shows that colorize things to make it look like another planet.
But Genoa realizes that and have a High Bright gamut - which is closer to HD spec.
The Red is a less pale Orange - causing Magenta to be pale as well - combined with a paler Blue. Give them all a B - but you can see they made the dark colors pale because it improves brightness.
The lighter colors Cyan, Yellow, and Green - they have oversaturated a bit - because Cyan and Yellow are used to create white they can afford to do this with the brighter colors. The hues are pretty good - also give them a B.
As a result the greyscale is not bad - give it a B+ for being just a bit Cyan.
I have seen worse color/greyscale points on other projectors - as a calibrator though I strive for an A - as I can see the difference to the point of annoyance. I would consider a B projector OK if you don't care about videophile stuff and are budget limited, but only an A projector would be highly recommended.
You can see the compromise in the gamma. The gamma curve is higher value and the blacks are crushed (or whites are popped depending on your viewpoint). I would give gamma a B as well.
So bottom line - the real point of these CMY colorwheels is to improve brightness - at the expense of a videophile calibration on greyscale/colors/gamma. In other words the usual game - market the big numbers - not the videophile numbers. Using them for wider gamuts makes little sense - no brightness improvement - but wierdly pushed colors for HD sources.
