"Samuel R. Delany described it as "about as close to an SF-style alternate history novel as you can get.
Further, while it incorporates elements of the fugitive slave narrative, Blake’s narrator is also a scientist, whose focus on data collection and research stand in repudiation of the racial science of the day.[10] In fact, this reflects one of Delany’s major themes: that Africa and its contributions to science and math were foundational to the Western world.[12]"
Considering we’re talking about the era of the belief in Drapetomania, I’d say a slave revolt followed by an attempt by black people to take over Cuba would be considered sci-fi by a lot of readers.
You should edit the wikipedia entry then, because it disagrees with you.

Because one author says so does not make it so.

Edit: Also, sci-fi wasn’t really a thing in 1862.
