I think the facts at least are as described. Hermione is certainly lying in a pool of blood, something significant did happen to her (Harry felt the magic), and Dumbeldore definitely believe Hermione is dead.
If there is a time turner involved, it won’t change those perceptions one bit, And I doubt Dumbeldore would try too Mess With Time ever again (as mentioned in the Azkaban arc). Harry might, but he’s out of his Time Turner Authorized Range. Even then, it looks like he’s thinking longer term than that.

Making Hermione a horcrux in the last 6 hours of her life doesn’t violate any observed facts.
