That's "Return of Bruce Wayne". Actually, IIRC, that story has the Kane family theorizing Thomas faked his death, but Martha was killed.

It also falls flat because Return is New Earth and Court of Owls is Prime Earth. And while many things were carried over post-Flashpoint, Batman's death and return at the hands of Darkseid wasn't. So what was once canon is no longer canon.

Also, the movie makes several deviations from the comics. It's just intended to be a movie in its own merit.

And sometimes, a woman is just a woman. The lack of diversity in female faces in animation is a long story. Don't think too much into it.
