No, it's canon. The author made a comment about it.

Sarada had personal tutoring from a number of Jonin, one of them her mother, while Sasuke had nothing due to the fact his family died. All he knew was Fire Release, and that feat is in-and-of-itself extremely impressive.

So we are to assume she has already trained to gain Lightning Release prior to this arc, which would make sense seeing her dedication to become Hokage.

Sarada also had a huge repository of knowledge, and had prior training with her Sharingan whilst Sasuke did not, having awoken it in the heat of battle and knowing nothing of it's capabilities.

However, yes, Sarada seems to have massive stores of chakra...

The next Madara maybe? Huehuehue
