There are many projectors that have excellent color reproduction like the HD10K that don't have a color management system so I wouldn't be too worried about it. I'm more worried about the quality and spread of the physical primaries which determines the full color gamut. I may be mistaken, but I don't think a color management system can correct for the physical primaries being suboptimal. Bottom line though I agree with you that a color management system would be nice.
Yes, I am referring to RGBCYM. I think its a given these days that just about every pj by default provides a color gamut that is quite a bit wider than Rec 709. So to account for this oversaturation, adjustments are necessary.
Here's Greg's quote from the Pearl review I am referring to:
"I hoped that the RCP function would
allow the primary colors to be set to the
Rec. 709 and Rec. 601 standards, but that
was not the case because it doesn't provide
independent brightness and saturation
adjustments for the colors.
Because the primary colors are more
saturated than the Rec. 601 or Rec. 709
standard, flesh tones occasionally appeared
too red. A good alternative to reducing the
Color saturation setting, which affects all
colors, is to lower the intensity of the red
primary slightly, using the RCP function."
I am hoping JVC provides us with real color management controls so that such things can be adjusted correctly. So even though the brightness does not fall on the CIE diagram, individual control over both the Brightness and Saturation are necessary to properly dial in the colors...
