I have used 120 films from both Kodak and Ilford for years, and I find that, at least with this format, the Ilford films usually exhibit this more "matte" surface, while Kodak's are always glossy, or shiny.
It seems to have no effect on printing, so I don't let it bother me. I say "usually" because I no longer pay attention to it, and am using exclusively Ilford film now.
