These two functions give the same result when the mesh is provided itself, or an object that uses the mesh.

NOTE: This may be higher or lower than the number of material slots on the object or object-data. However, it is always at least 1 (the fallback).

On evaluated objects the number of materials on an object and its data might go out of sync. This is because during evaluation materials can be added/removed on the object data.

For rendering or exporting we generally use the materials on the object data. However, some material indices might be overwritten by the object.
