Need help with VT50 Calibration

I posted this in the Plasma forum and cross posted here looking for suggestions with my calibration of a 65VT50 with ChromaPure and ControlCal.
Any help would be greatly appreciated.

These are my newest reports for Cal Day & Night. I'm pleased with the Night results but I can't get a grip on the dE in the gamut on the Day. In the Cal Day I ran the color down to 43 to try to even out the luminance errors. The only thing I can think of that is different between the Day and Night modes is the Contrast setting. I have it at 86 for Day and 82 for the Night. My max output on Day is 41+ and on Night is 34+. With the Contrast at 86 I am blowing out the 256 bar and on the Spears and Munsil GetGray ramp I do see a tinge of color in a couple of bars.
Can the Contrast setting affect the color that much? I'm just not sure where to turn with this.
Please if anyone has any suggestions please give them.

Thanks

BTW I'm going to cross post this in the Calibration forum.

FYI the Color setting in the Cal Night is 46

I guess I need to delete the Day and start over on it. Cal Night looks great though. I do notice some color differences when I pause a picture and switch from Day to Night. Day looks to be a little less saturated.
