Hmm yea pretty much they evolve thier uses and strenght most times appearance! But its the same ability!!!
luffy advanced his rubber ability so he can now use it to improve his speed strenght and appearance this is why I say he "evolved" past his standard capabilities which were just streaching his limbs to throw a punch or what not.

megellans poison ability evolved pass normLy poisoning people but is able to corode and destroy the stone walls of ID though it wasn't stated this is why my theory has reason to believe he trained his poison ability to do so
