The ISF picture mode is not interchangeable with technicolor Expert. technicolor Expert uses an alternative white point vs. ISF. ( Don't get me wrong - ISF is a great picture mode, but its behavior is very different when calibrating. ) It takes a lot more adjusting to get ISF's white point correct, and even more adjusting to the CMS. You may notice that my settings are all single digit for 2/20 point, and CMS. That's because technicolor Expert is more accurate at default than ISF, so I don't have to do as much adjusting. I found an old post from October 2017 in which my shared settings were based on an ISF picture mode. Below are the CMS adjustments from that post. As you will see, they are quite a bit different from the technicolor Expert CMS adjustments. In fact a few of them are in the double digits:
COLOR MANAGEMENT SYSTEM
RED - Sat: -12, Tint: 8, Lum: -4
GREEN - Sat: -7, Tint: -30, Lum: -1
BLUE - Sat: -3, Tint: 9, Lum: -1
CYAN - Sat: -11, Tint: 5, Lum: 0
MAGENTA - Sat: -3, Tint: -7, Lum: 0
YELLOW - Sat: -6, Tint: -6, Lum: 1
My advice would be to not make any adjustments to the 2/20 point white balance, nor the CMS as they are not going align with the ISF picture mode you are using. Remember, almost all of my settings are borrowed by P4OLO for his postings and he is not a calibrator.
EDIT: At least the last time I checked.
