So, i took a look at Identity-Selector-Interop-Profile-v1.pdf

Yes, that particular profile is apparently stipulating use of a pair-wise 
pseudonym between the IDP and each RP. See e.g. 4.3.4. Client pseudonym.

That doesn't mean it has to be done that way in any companion profile that's 
cooked up. Nor does it mean that an RP cannot facilitate the user's setting of 
whatever "display name" the user wishes on that site.
