Question about the "leaked" storyboard

Sorry don't know where else to post this. I read the leaked sesbian lex Jail Scene storyboards were confirmed to be fake?

Edited to add where my confusion comes from:

1) I read that the person who made it knew this was the scene nominated for some kind of storyboard award, so I'm confused how they could know that if the leak was fake 😕 (points to being real)

2) Some folks pointed out that the scene is the same length as what aired, which Christian Linke said it was longer. (Ponts to it being fake or altered)

3) I guess there is also a style difference between the storyboard and the artists nominated for making the storyboard....so idk. (Points to it being fake or altered)

Does anyone know if the leak was proven to be fake or not?

Sorry if this isn't the right place to ask 😅
