The only thing he may have lost is the ability to don the upgraded Chakra Mode for SPSM, where he draws the power from every single tailed beast and essentially goes into a pseudo-ten tails form, though this has not been confirmed nor ever stated. Though it could have literally just have been a design change and was indeed using the same mode, but again, never confirmed.

Just because he didn't use it, doesn't mean he doesn't have it.
