Primary screen not listed in Gnome color manager

Interestingly, my primary notebook (DELL XPS 13, 2015 model, Intel GPU) runs Fedora 22 (Gnome 3.16, gdm 3.16.3-1, colord 1.2.10-2, gnome-color-manager 3.16.0-1) and does not suffer from that problem. Screenshots:

The bug exists even when no proprietary drivers are used. Screenshot:

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm this bug from Ubuntu Gnome 15.10, after all newest packages installed. This did not happened in 14.04.x and 15.04.

There is a terminal command:

colormgr get-devices

I wonder it list anything on 15.10.

colormgr get-devices only lists my printers, i.e., it does not list my primary screen.

I dicovered that "sudo colormgr get-devices" listed my devices, while "colormgr get-devices" does not. Is this a privilege issue?

I upgraded to colord 1.2.12-1ubuntu1 from Xenial and this issue is solved after that.

I am now running kernel 4.2.0-23. The problem remains.

I'm seeing the same on a freshly installed system. I'm seeing the same as Tyson in #8, where I can get all the attached devices as root but not as my user:
