Once he acquired both element halves and fused both elements back together, he had YinYang Kurama.. Kurama has no normal elements because he has YinYang release. So when Naruto got YinYang Kurama his SPSM Kurama Cloaks changed. Therefor he turned into Six Paths Sage Mode, then he used his new Kurama Cloak which is different.. plus the Hashirama Chakra/Arm may change his chakra signature and remember his chakra was slowly fusing with Kurama's the whole time so that may have had something to do with it too. That doesn't really explain why the forms changed in between Gaiden and Boruto the Movie. Unless you are suggesting such fusion happened long after Yin and Yang Kurama fused and Naruto gained the arm made from Hashirama's cells.
