OK, so see if the following tools let you calibrate and
profile a display:

Sorry for the broken e-mail. I was unsubscribed at the moment. 😳
But I guess it's nice with some feedback.
I unboxed my first ever mac yesterday (macbook air 8 256 m1) and have tried
your beta. It works very well, I think. Since I'm an absolute mac beginner
I spent too much time before I realised that I had to run the entire
terminal under rosetta. If not tools like dispcal would crash at the end
like this:
*Computing update to calibration curves...\*
*The instrument can be removed from the screen.\*
*zsh: segmentation fault dispcal -v -ql -o Targetlow}%*
If anyone is curious here is the uncalibrated response from my rosetta
terminal:
*dispcal -R*
*dispcal: Warning - CFDictionaryGetValue(kDisplayProductName) returned
NULL!*
*dispcal: Warning - new_dispwin: Frame buffer depth 8 doesn't match
VideoLUT 10*
*Place cap on the instrument, or place on a dark surface,*
*or place on the calibration reference,*
* and then hit any key to continue,*
* or hit Esc or Q to abort:*
*Calibration complete*
*Place instrument on test window.*
*Hit Esc or Q to give up, any other key to continue:*
*Uncalibrated response:*
*Black level = 0.1030 cd/m^2*
*50% level = 19.49 cd/m^2*
*White level = 89.16 cd/m^2*
*Aprox. gamma = 2.19*
*Contrast ratio = 866:1*
*White chromaticity coordinates 0.3072, 0.3281*
*White Correlated Color Temperature = 6819K, DE 2K to locus = 7.4*
*White Correlated Daylight Temperature = 6819K, DE 2K to locus = 3.4*
*White Visual Color Temperature = 6514K, DE 2K to locus = 7.1*
*White Visual Daylight Temperature = 6687K, DE 2K to locus = 3.3*
*Effective Video LUT entry depth seems to be 12 bits*
*The instrument can be removed from the screen*
*dispwin installs the profile, and they are available and selected in
"system preference" - Display - colour, but I have not tested much there
yet. *
*Great job.*
