What does its belly look like? If it has checkers on its ventral scales then it isn't a motley.
Banded is a selectively bred form of motley where the patches on the back blend with the side patterns to make it look like a 'band' around the snake. The picture is a little unclear but it looks like there is a gap between the back and the side patterns, if so then I wouldn't call it a banded, just an amel motley if its belly has no pattern on it.
