I haven't watched that movie, but I did look at screenshots, and what I see is the bog standard black hole used by everyone everywhere. And I'm not really surprised - after all, Interstellar invented the black hole image this article was talking about, AFAIR it was for this movie that such rendering was attempted the first time ever - so for your reference to be relevant to my comment, we'd have to be dealing with some really serious time travel stuff. ;).
