After doing it the second time, I feel confident that you are right. The color shift is even more diminished... I can only see it now very faintly on black and white content, which really doesn't even need it. It is now brighter than it used to be, additionally. It's really excellent, thank you again.haha, you didn't ruin it, quite the opposite. You fixed a problem and tuning that sensor to D65 resolved a 10 year old issue. Look up any discussion on the 750 -- color shift with the LED dimming is usually mentioned. no solutions until I stumbled upon it earlier this year.
The calibrator can read the details provided in the thread, there is always opportunity to learn something new regardless of previous experience.
