SUMMARY


STEPS TO REPRODUCE
1. Enable night light with a strong noticable warm color temperature so you can easily tell if the screenshot has been affected (I am using 3000k)
2. Take a screenshot (I've used https://commons.wikimedia.org/wiki/File:SMPTE_Color_Bars.svg opened inside Google Chrome
Version 144.0.7512.1 (Official Build) dev (64-bit)) 
3. Turn off night light
4. Take another screenshot

OBSERVED RESULT
Compare screenshots, notice the first screenshot having different colors than the second one

EXPECTED RESULT
Compare screenshots, both screenshots should look identical.
