The name changes of that paper were EAM>EEM>EUPPM=Epson Ultra Premium Presentation Paper Matte but not everywhere.
If it looks good for you there is no reason to profile it all over again.
However you can not profile for the white/color shifts in time which was the main reason to change the name from EAM to EEM.
