It is probably slightly different. Most NMR signals have a chemical shift that is solvent dependent, and the difference between dmso and solid state is presumably much greater than the difference between dmso and D2O. That said, I doubt there would be a huge shift unless the coordination environment of the Al is substantially different in the solid state than in dmso solution--dmso is Lewis basic enough to be a good ligand, and would likely coordinate strongly to trivalent aluminum species, and could potentially displace weakly bound ligands (like bromide or triflate)...

Thank you Aaron Bloomfield sir.
