In my humble opinion, an example of it distinct from Creation's usual and that would feel better to list as "Materialization" is when Characters can Materialize thoughts, memories or the fears of others, etc. Finally, an argument to calling nearly every power page redundant could be made, if we are to not make them based solely on a prior one being a widely expansive umbrella. E.g.: There would be reason to remove Fire, Water, Wind, Lightning manipulations and etc, since Elemental Manipulation + Explaining which in the page would cover for any of these powers on its own. Yet they are useful to have, because they make things more to the point, direct and clear to understand.
