Digital BW, The Print

We all know about the weird practise of naming the same produkt 
differently in the US and the rest of the world. Is Epson doing it with 
papers as well printers? Or do they just sell different stuff in 
different places?

I live in Sweden and there's no
-Enhanced Matte
-Ultrasmooth
-Premium Lustre
-Velvet Fine Art

What's the deal here? Is for example Enhanced Matte the same as 
Archival Matte? Can somebody straighten this thing out, please?
