macOS calibration affected by currently installed profile

[Emil Ingelman Sahlen]

Hi,

When using displayCAL to profile my display, it seems that the measurement is actually affected by the currently installed ICC profile. I can tell this because when I am doing “Interactive display adjustment”, the RGB meters show completely different values depending on the profile I install before I start calibration. As far as I understand, the calibration should be unaffected by the current profile.

Is there something that needs to be reset beforehand?

OS: macOS Monterey 12.1
Computer: MacBook Pro 14″ M1 Pro
DisplayCAL version: 3.8.9.3
ArgyllCMS version: 2.3.0

Seems like the problem was cause by TrueTone. When I disabled it, the problem is fixed.
