I posted in the calibration section and got some responses- http://www.avsforum.com/avs-vb/showt...1#post21965131
Check out the link in the 2nd post for a great tutorial. Basically the jist of it is to calibrate CMS based on 75% saturation (NOT 75% brightness windows) These are on AVS 709 in the saturations section (bottom right of HCFR windows section). Although I'm a little over saturated at 100% saturation, the curve is way flater from 0 - 75% saturation. Its a good compromise and subjectively it looks better. Less greenish with a warmer feel and a little more punch in the colors. Flesh tones look ultra realistic now!
And yes we can set the 100% white Y value higher than 100 and then just adjust the rest of the colors off the recommended % of 100% white Y.
What I was missing was I had all my xy coordinates dead on using CMS but the Y value (brightness of each color was off). In other words you can have the correct ratio of colors but not enough total brightness. E.g. If your red was at 20, 15, 10 that might be the right mix to get xy accurate but if the Y value is too low you might have to bump everything up 25, 20, 15 (same ratios, but more light out put) to get the Y value correct.
In HCFR you can run saturations ---> All colors to see where you stand and then tweak from there. You'll see results on the CIE triangle, saturation - shift graph and saturation - luminance graph. Saturation-luminance was a little tricky. I could be wrong but it almost seems like for Red, blue, and cyan (at the bottom, increasing Y value makes them go up and decreasing Y makes them go down. However, and I could be wrong, for Green, cyan, and yellow, increasing Y value makes them go down and decreasing Y makes them go up. I could be wrong but I think that's how it behaves.
I'm still learning so if anyone who knows more than me can verify my interpretations I'd find that helpful
P.S. The saturation - luminance attached was on my second run. I did it a 3rd time and by increasing output on RGB for green, it raised my Y value but decreased the saturation-luminance - you'll see on that attachment that its way too high. I'll post my recalibrated one this evening when I get home from work.
