I don’t think that fictionality is orthogonal to notability. I do think that something that occurs in fiction is inherently less notable than the equivalent event occurring in real life no matter how popular the work of fiction. I agree on the second point but fundamentally extensively in depth information about the inner workings of a fictional piece are best acquired from the work itself. Not gleaned from an encyclopaedia.
