Fantastic sleuth-work, but I insist that it'd be disingenuous to act as though The Dalek Tapes putting all this info at a remove made the originals’ veracity questionable.

Since Genesis of Evil itself is presented as unquestionable in-universe events rather than a version of history that is itself at a remove, what we have here is one story (Genesis of Evil) saying one thing in earnest, and then another (The Dalek Tapes) having a character find old records which may be reliable, but are in point of fact consistent with said thing.

In other words, instead of

An individual once recounted or found evidence that indicated the Daleks were created as a result of a similar catastrophe but without Davros's influence (COMIC: The Dalek Tapes) from a race of blue humanoids. (COMIC: Genesis of Evil) The Doctor discovered these tapes many years later in an ancient library on a twilight world. (COMIC: The Dalek Tapes)

we'd have

According to some accounts, the Daleks were created as a result of a similar catastrophe but without Davros's influence, mutating from an ancestral Thal-opposing race of blue humanoids. (COMIC: Genesis of Evil) Another account showed that an individual once recounted or found evidence of these events, retelling this history of the Daleks in the Dalek Tapes which the Doctor discovered many years later, in an ancient library on a twilight world. (COMIC: The Dalek Tapes)

This seems like a similar situation to this recent short story that claimed that Destiny of the Daleks never actually featured Romana II, but rather the TARDIS's soul posing as her. I don't think we want to follow these kinds of in-depth retcons to decades-old stories blindly. It must be "one account says that Romana II did this, this and that upon regenerating (TV: Destiny of the Daleks), although another account stated that these actions were instead undertaken by the Doctor's TARDIS in human form. (PROSE: The Lying Old Witch in the Wardrobe)", for the sake of our collective sanity. Well, this is the same thing.
