Thanks again David, things are starting to get clear to me.

The only thing I still can't understand is the fact that, after calibration, when using a non color managed app to view a picture I can drag that picture from one display to the other and the colors look almost identical but if using a color managed app like Photoshop or Lightroom when doing this there's a color flip and the colors suddenly look different.

For example if I have Lightroom in thumbnail view on my main display and have a fullscreen view of the selected thumbnail on my secondary display, the colors are not the same, that's not logical to me, doesn't make sense.

I can see that the calibration affects everything on the screen, so the correct thing is to use the profile in the control panel and also to have the calibration on all the time?
