Hi Damien,
I am recalibrating for the first time since upgrading to High Sierra. I have a colormunki and have not had many problems doing it before today. I have change the white point 3 times and the screen is not getting any warmer. As a matter of fact I can see no change at all in the silly before/after thing they have you look at. And of course my screen is way cooler than my prints.
Excuse the crappy iphone pic...
