Re: Possible ColorSync discontinuity bug introduced in OS 10.14.6 with display "r/g/bTRC" tags?

Anyone at Apple aware of this?

I*’ll ask around.

After the update I cannot trust what I am seeing on my iMac 27” 5K. Color and contrast are washed out,

Sounds like the profile and/or LUT associated with the display changed after the update, maybe reverted to the factory profile (the one created at login). Open System Prefs - Displays and reselect the profile you’d chosen before, even if it’s already selected in the list. If the display appearance changes, that’s what happened.
