Continuation of comments regarding darkening of screenshots in some apps.

So, what i suspect is Apple’s Safari (web browser) is better at handing off the correct color profile than RawTherapee, which maybe doesnt pass along anything to Screenshot profile-wise, so it may be defaulting to my or some other incorrect (monitor) profile.
