Has Sanji mutated?


So from the recent manga chapters I know that

> Sanji is the third son of the vinsmoke family and like his brothers he
> undergone a surgery as a fetus and has had his genes mutated. But due to
> drug his mother took he developed compassion and did not mutate while he was
> with his family.

So has he mutated over the course of his adventure or would this be a place
for him to gain power from in the future?




He may have in some capacity and that may be revealed as the current arc
(whole cake island) progresses. But currently no he is not mutated.

His father states this during their battle when he first left the straw hats,
calling him weak and stating that he is suprised that Sanji is even able to
use haki in his form.

During that battle and the other scuffles he's had with other siblings too,
I'm sure that if he had undergone some sort of mutation it would have been
brought to light by now.

In summation, Sanji is regarded by his father and siblings as the failed
project because the mutation never took effect on him.
