@rgb If I understand the problem correctly, there is no problem. RGB is a model that allows you to display the maximum number of colors in the digital world, using 3 coordinates. The inconsistency of the usual understanding here is inevitable. CMYK looks flatter simply because it is (I don't know how it's done, but usually) a conversion to a model with less coverage and then back again. The conversion algorithms have worked twice while doing this. You don't have to do it that way.
