That is because the material is referenced by the mesh that is passed into geometry nodes and not by the object itself by default. The primitive node has no knowledge about these materials currently.

Currently, the solution is have the object reference the material (instead of the mesh). Then, whatever mesh comes out of geometry nodes will use the material of the object.

I hope that we can improve the material handling in geometry nodes soonish, but that won't make it into 2.93.

I'm closing this, because it is not a bug.
