Nothing can fully correct a video display that can't achieve 100% saturation for red, green, or blue. Those are the 3 primary colors you measure and calibrate with a CMS. If these colors are "inside" the Rec709/HDTV color triangle, no processor can move the measured points farther out (increase saturation). You have some issues with red and green and blue saturation... all of them are essentially "inside" the color triangle. This could be a result of not starting with the correct mode or perhaps having the Color control turned down too far or some other setting. You should also NOT be using a color filter to set the Color control... no matter what anybody says, the filter method is nearly a complete waste of time. Every set of instructions for using a color filter to set the Color and Tint controls always says something like... if the color or tint do not look correct after using the filter, readjust them until the images look more natural. You do that readjustment BY EYE without a filter. So why not just adjust color and tint by eye in the first place since there are so many variables that cause the color filter method to fail when it LOOKS to be properly adjusted.
So just because you used a filter doesn't mean you have the color and tint controls adjusted correctly -- in fact, your measurements indicate that both controls are probably mis-adjusted.
Using the matrix calibration capability, the video processor (Radiance in this case) should be able to correct the measured position for any point "inside" the Rec709/HDTV color triangle except the 100% measurements. If you start with the 100% measurements at the correct points or "outside" the triangle (may be possible with readjustment of Color and Tint), those points will ALL (100% and everything below 100%) be calibrated correctly by the CMS autocal.
