Alright, so been searching about but still can't find any solid info about it. Does anyone know if the box legends for ORAS are shiny locked?

I know the Lati@s you get given has a chance of being shiny, but what about the other legends. Can the box legends or any that are found on mirage islands be shiny?

pls help I want to see if I can soft reset for pink bubblegum whale
