>>Thank you very much David and also thank you to Laurie.

You are welcome...

>>I was asking about double profiling because if I disable the calibration on the spyder utility I get one type of colors but if I uncheck the "use my settings for this device" switch on the control panel app I get another type of (on color managed apps ligk Lightroom) and if I have both on I have a third type of colors.

Correct. Think of a preflight checklist: Calibration on, check. Profile on, check.

>>So if I understand you the profile loaded on the control panel (generated by the spyder software) is what color managed apps use. 

Yes.

>>And the calibration is separate thing?

Separate, but related. And stored in a tag in the profile for convenience. And applied at the video card level.

>> 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?

Yes. 

>>That isn't aplying double transformations to the pixels?

An intended pair of transforms that add up to full display color management.
