Um you mean a downgraded version of RSM, no. It was Karuma's chakra.
Whether it was enchanced or not is still unknown, no need to make a false claim...again.
The topic from further arguement is whether Naruto completely mastered everything with rsm right away or not compare to little trained sharinnegan.
Here is how i destroy all your claim with actual manga fact.
Naruto didnt know back then that he can fly.
Naruto didnt know the detail how the creation of all thing work, he just did it with his instinct, not fully mastered yet.
Naruto didnt know how to shape form of black orb back then to use as a shield like a rsm user.
Those 3 points alone to destroy your theory about fully mastered rsm user vs little knowlegde trained sharinnegan.
They clearly act on their instinct but not fully mastered with new powers. We havent know if Naruto is fully mastered rsm now or not, that is up to the movie or future project.
