No, the shadow is confirmed to be Zunisha. I think the problem is how the conversation with the Gorsei is being conveyed. It might have nothing to do with Zunisha. Unless Zunisha is a DF user (which i don't think it is), they might not even be talking about Zunisha.
Seriously read the spoiler again and try to separate the shadow stuff from the gorosei conversation, you might come to a different conclusion because the Korean provider never specifies who they are talking about. There is another translation in the thread to which combines the whole awakening thing with the devil fruit line.
