Color Temperature of iMac Monitor

I have recently calibrated my 2017, 27" iMac monitor using Spyder X Pro and saved this new profile. It was carried out with Ventura 13.4 OS. This calibrated screen is much more orange than the default iMac monitor, which is very blue. I would like to measure or determine what the color temperature (in Kelvin) is of both the original color profile of the iMac monitor and the calibrated version. Which app do I use to determine this? This info is not available under 'Displays' in 'System Settings' nor under 'Hardware' under 'About This Mac'. Thank you.
