nah it’s at this point kinda an obscure fact because originally ditto was able to transform perfectly, but in the anime they centered an episode around this ditto who couldn’t fully transform and always was stuck with the ditto face. for whatever reason, that version became more popular, so at this point sometimes they portray them as always having the ditto face while other times they can have a perfect face

In the anime episode it was pretty obvious that that specific ditto wasbas at transforming and most ditto could transform their face, I don't know why thar isn't common knowledge
