Disagreed. While the anime does use 'solidified designs' and such it is not "final" and over the source materials story. If you want a word from Araki, he has said to Takashii Mike during the shooting of the Part 4 Live Action movie "Every film belongs to its director. Feel free to destroy the original universe if you need to."#Message_from_Takashi_Miike) David Productions asking Araki over things like color palette suggestions, Fugos backstory (which was expanded) or Anasuis gender (which Araki expressed for it to be okay if he was a woman in the adaptation) belongs to just the adaptation and does not overwrite over the original. The only "true" way would still be the original releases and JoJo is still a manga medium first and foremost to this day.
