Six Paths Sage Mode is characterised by the crossed pupils without pigmentation around the eyes. There's also the Rinnegan and the nine magatama on Naruto's back, but in Gaiden, they weren't there. If you ask me, it was Kurama Mode mixed with SPSM (without the other eight tailed beasts' chakra, otherwise I think we'd have seen the Rinnegan and the magatama on his back. 9 magatama=9 tailed beasts).
