Possible to check if a pokemon is edited with Pkhex?

[Rune Knight]

Is it possible to check if a pokemon is edited with PKhex? (Edited IVs,EVs,Shiny and so on)

Will there ever be something like a legit checker for gen6 ( and maybe 7 later)?

[Kaphotics]

PKHeX has a legality checker built in for gen6 Pokémon.
