Addition: "Automatic" was probably broken by the intel driver before
too. I just found an entry I made in /etc/X11/Xsessions.d which set "RGB
Broadcast" to full, which now didn't worked anymore because the
device/port is now DP-1 instead of DP1.
Nevertheless, somewhere is a bug, either in RGB-range detection or my
monitor is reporting a wrong range.
