Bug description:
  After upgrading the Xenial kernel from 4.4.0-31-generic to
  4.4.0-34-generic, custom ICC color profiles are no longer being
  applied. I am adding them from System Settings -> Color. I am
  experiencing this bug for monitors, both the laptop screen and an
  external screen plugged in via HDMI.

  If I boot into the old 4.4.0-31-generic kernel they work just fine. I
  am running a Skylake system and I saw that the i915_bpo module is
  rebased to v4.7-rc6 in the latest kernel so I am guessing it has
  something to do with this update.

  UPDATE: I found a workaround: The ICC profiles are actually applied if
  you turn a display off and back on again via System Settings ->
  Displays. The switch in System Settings -> Color still makes no
  difference what so ever.
