Lee, after I had more time to work with your settings with CCA sensor status information you sent me. I had found and corrected my issue with moving Desaturation yellow down way below yours. I posted my settings for you to look at the bottom portion of this reply.
I had to move CCA Red and Blue Y values to OEM service manual defaults, and keep your Green values untouched. Then adjusted Blue-Y to get the sensor values as close to yours as possible with out making Green go beyond 147. I then moved Red-Y to get R-145, G-146, and B-154.
As you know I get grey by getting all the RGB CCA sensor values to match equally. So I noted that when the screen flashed durring the CCA save that the white was tinted redish. I was able to then balance the Desaturation settings to the best I could with the Red and Green filters.
I noted that the CCA sensor values changed after getting done with Desaturation, and continued to manualy adjust Blue and Red Y to get the CCA sensor values to match.
After that I re-did the Desaturation values to get the best color filter settings. Again, moving Desaturation around will need to recalibrate CCA if using my method.
I now have most of your values working though I did not expect them to work as well. Since my calibrating had shown the settings would move away, not move closer.
I think the issue you wrote about (when saving a CCA value), causes the menu to go into a funky blue mode, is from pushing a color into beyond saturation mode in the CCA. As I explained before, you can move around up or down the coordinate and still get a result (I am not sure but after increments of 10 the color level becomes cyclic). That caused me to think about moving down on the Y as it affects overall gain of the primary color.
Here is my settings with CCA sensor values equal at 154 (having one color + or - 1 is ok), as you may see about 80% mirror of yours:
*Red-Y:94.1 (moved up from Lee's setting)
**Red-Y:82.8 (moved up from OEM default)
***Red-x:701 (perfect CCA sensor setup for my TV)
***Red-Y:93.3 (perfect CCA sensor setup for my TV)
*Green-Y:282.2 (moved down from Lee's setting, as the last part of getting CCA correct from Desaturation adjustments)
**Green-Y:282.4 (very small tweak to get CCA sensor status near equal after Desaturation adjustments)
***Green-Y:282.1 (perfect CCA sensor setup for my TV)
**Blue-Y:29.7 (moved up from Lee's setting)
**Blue-Y:27.0 (moved up from OEM default)
***Blue-x:137 (perfect CCA sensor setup for my TV)
***Blue-y:50 (perfect CCA sensor setup for my TV)
***Blue-Y:29.0 (perfect CCA sensor setup for my TV)
*Red-x:640 (OEM default)
*Green-x:295 (OEM default)
*Blue-x:150 (OEM default)
*Blue-y:60 (OEM default)
**Cyan-x:217 (Slightly lower than Lee's)
**Cyan-y:225 ~ 230 (Slightly lower than Lee's)
**Magenta-x:343 ~ 350 (Higher than Lee's, and closer to default)
**Magenta-y:163 ~ 170 (Higher than Lee's, and closer to default)
*Yellow-x:422 (OEM default)
*Yellow-y:500 (Any higher adjustment would not effect yellow, as it is close to calibration)
**Yellow-x:450 (A little lower than Lee's)
**Yellow-y:550 (Any higher adjustment would not effect yellow, as it is close to calibration)
