As far as I can tell from my linux install, marking that checkbox
overrides whatever display profile you selected and uses the profile
installed in your current user.
I'm not sure if other platforms behave the same, but that's how it
works on Linux.

Having selected a display profile from disk doesn't result in a
redundand or harmful adjustment, as it's just ignored when that checbox
is set.

I guess it's easy to check if that's working in your system:
Just set the display profile to none, and mark the checkbox, then flip
between "color managed display" and "no color managment".
If there is a change, then your system color profile is working.
You should get the same change turn on and off the checkbox (and your
monitor display is set to none).
If you set manually the same display profile your system use, turning
on and off the checbox shouldn't make any difference.
