That's the issue with the Elite, very poor color tracking for most of the primaries and secondaries. You will need to make sacrifices at high saturation levels in order to bring low-mid levels closer to spec. :S Also need to view actual content after calibration to make sure the colors 'look' right.
This is what separates DIYers and professional calibrators. Some TVs can be perfect with lower than 1 dE on all points after a calibration but actual content reproduction does not reflect the calibration. Professionals can adjust the set knowing how a specific scene should look like based on experience.
I did a 70" on Tuesday this week. I don't even attempt calibrating at 100% saturation anymore, rather use 75% saturation, 75% luminance. This brings luminance in at about 50% of full 100% white and it's where you want to be. 100% saturation will be off but you'll get much closer to correct where the vast majority of content lies.

The 125 point 3D LUT fixed my cyan problems. Actual color points measured are 123. Measured de's from 25% thru 100% at 5% intervals all have de's less than 1.5 with exception of yellow at 35 & 40% and again at 60 & 65%. Yellow at those points is around 1.7 to 2.2 as I remember. Picture looks great.
You can do better still with an eeColor Processor or SpectraCal ColorBox - actually, they're the same thing. The very best LUTs are produced by LightSpace software using 4913 color points for the profile, but if you have CalMAN Cube ability you can choose something like this for much more accuracy than the 125 point profile. You can choose any dE you like and really work it down.
This yields the attached report. Not from an Elite, however, as I've had no requests for Elite 3D LUTs yet - their loss....
