I'm not saying that all Pearls are identical OOTB. They are not, or else we could all just use the same settings. But the cartoonish appearance of wide color mode is the problem I am having, and this is consistent with end-user reports and with professional reviews which report that the Pearl cannot be calibrated for luminance and gamut simultaneously.
It also explains the normal mode "filter." According to GregR's review, the normal color mode decreases red luminance significantly and blue to a lesser degree. This gets rid of the cartoonish appearance, but compromises color brightness. I believe that normal mode exists specifically because of the oft-cartoonish look of Wide Mode.
