Unless you know some highly connected and unsavory people you have 0% chance of owning a pure jungle. All jungles were crossed with coastals prior to jungles being recognized as a subspecies. Assume any carpets you by in the US, including zebras, as being crosses of some kind. The jungle traits are hobby assigned ideals, no matter what anyone says. Plus genetically the difference is minimal.

It's a beautiful and healthy animal, that's enough for me.
