Well the Six Paths Sage Mode is the product of Six Paths Chakra, Senjutsu Chakra and the Nine Tailed Beasts Chakra. The mode used in Gaiden is the product of Six Paths Chakra, Senjutsu Chakra and Kurama's Chakra alone. As for the Coffin Seal, it coresponds to the Nine Beasts together, not for Kurama alone, that's why Naruto doesn't have it this time, while cross pupil minus the pigmentation corresponds to Senjutsu Chakra and Six Paths Chakra.
