I understand that getting the EDID data is unreliable at the moment.

In addition, some wide-gamut displays support pre-set calibration modes
emulating various colour spaces. The modes can be changed via hardware
buttons on the LCD.

For the time being, I would leave up to the user to select the proper
display profile (depending on the attached monitor and its calibration
mode) rather then only relying on EDID.
