Difference between Lv. 1 and Lv. 100 EV training?

Question

If a level 1 Pokémon was fully EV trained, then raised to 100, would it be different between a Pokémon that came at level 100, fully EV trained? After it's already trained, does leveling it up effect it's growth? (same nature and IVs)

Comments

no, there's no difference

Answer 1

There is a slight difference in the fact that in order for the pokmeon to gain stat points from the EVs it got it needs to level up, so if you train before lvl 100 it's the same as if you train at lvl 1.

However, this doesn't apply in super training since the Pokemon gains the points instantly, so you can do that at any level you want to.

But I thought  they changed that since black and white?
