Replacing Spark 720 2015 derailleur + hanger using markings
Derailleur hangers are typically made from a flat plate of alloy, and are not bent to position the derailleur in or outboard.

I'm guessing, but if you have the correct hanger I suspect you have it mounted on the wrong side of the frame. Googling the serial number for images of the hanger I see the hanger mounts on the inside of the frame and there is a matching plate that mounts on the outside.

The google images I found seem to match online images of the Spark. If your replacement hanger looks like those you probably have the correct part.
