It will be hard to tell what she is crossed with, but it doesn't matter. What a great pet to have. A nice, long lived carpet. I would not call her a "hybrid" at least in the sense most folks think about the term.
Carpets are crossed so often you'll never know exactly what you have unless you have data from the breeder.
Whatever Morelia Spilota mix you have there is a very healthy, well cared for animal!
I have some type of coastal cross and can only hope I have her as long as your new girl has been alive.
Congrats.
