they are different but Nagato's Rinnegan was in fact Madara's Rinnegan its likely that those Rinnegan were in fact immune to the effects as well. also since Madara could use the sharingan abilities had nagato known that he may have eventually learnt to use the sharingan abilities as well we know that a dojutsu can sync to another dojutsu case in point obito used his mangekyou to sync with kaguya's Rinne Sharingan so it may very well be possible for anyone with a Rinnegan to sync with the sharingan or Rinne Sharingan and as a side effect gaining access to the sharingan abilities
