Today my CCC prompted me there is an update available and suggested updating from my 14.something to 15.7 - I did it and now after restart, the colors look completely different. The blacks went into overdrive so anything black is pitch black now and dark photos are so dark all detail is lost. Overall contrast (or saturation) seems to have changed as well. I changed nothing in my monitor's settings or the system preferences but I also don't see anything changed in the CCC itself (says it's using system prefs). Anybody experienced similar thing and knows what's going on?
