I set up my equipment for some calibration runs last night and was hopeful to finally have a workable ISF Night mode. I had finally figured out how to skip or modify the 2pt grayscale in order to avoid the red bias and black crush that I was experiencing with previous attempts. However, I am now finding that I need to max out saturation on both Blue and Green. I can get still get delta E below 1.0 for Green but I am still low on saturation for Blue and the best I can do on delta E is about 3.0. And Blue just does not look right.
I made these runs using a D3 Pro that was profiled to my i1 Pro. I also ran thru a calibration just using the i1 Pro and the result was similar. I was using AutoCal in Calman5 but I went back and made some minor improvements (reducing luminance to increase saturation) using manual adjustments but Blue still looks wrong.
What really concerns me is that the very first time I calibrated the TV (using ChromaPure), I did have to max out saturation for Green but ended up with only +2 for Blue saturation. Other than using the two different calibration programs, the only other significant difference is that I used "Normal" color temp with ChromaPure and I used "Warm2" color temp last night when running Calman. I need to go back and try Normal for future runs but I did not think color temp could have such a significant impact on CMS settings.
Any ideas why a TV that is suppose to have relatively accurate colors out-of-the-box would require max'ing out saturation ? Anything else I should try other than changing color temp ?
