Reading term based user profile attributes

Hi there,

I configured a user profile attribute that is based on a term set. Now, when I read out the value from JSOM or REST I only get the string value. I really want to retrieve the GUID of the stored term, in order to read out additional data from the term store, like the parent term, custom properties, etc.

So, the question boils down to: How do I read out the term's GUID from the stored term in the user profile attribute?

[EDIT]

I also tried out the server-side API. Unfortunately, this returns the stored term as a string as well.
