I have a calibrated screen (Spyder Pro) and Photoshop uses my monitor profile.
I don't find a way to use a certain color profile in Xara though ...

Anyway, I don't think that it's about profiles.
The right (Xara) sample above was saved from Xara and imported into Photoshop.

And once imported into Photoshop it looks exactly the same as in Xara and has a totally different reading of CMYK values

Must be something different ...
