Sorry - the Modify/Extract function extracts the native colour space from the profile.
You can copy the values manually too.
The new colour space should ten be used to assess the profile, to see if its maps to itself well.
It if does, it just means the display has a low gamut.
If that is the case, you still calibrate to Rec709.
But, you may need to use something like 75% target colours.
You do not calibrate to the extracted colour space, as that would cause the calibration to not follow the required standard - Rec709.
