Yes, her name is listed as Shampa Gopikrishna in the Mahabharat videos.. Maybe Remo might have got confused with that Shampa and this Shampa and she didnt want to make him feel bad by correcting what he had said... Because this Shampa looks quite different from the Mahabharat one...
No, Remo was quite sure of it plus Shampa bowed, agreed and thanked Remo! I haven't seen the Mahabharat video so can't comment on that!
