That's possible. But amels have such a wide variety, and this one isn't that odd looking of an amel to be honest. As I mentioned earlier, some het caramels have a yellowish tint that can take over their body. But not all do. Though this one does have that coloration one might expect from an amel that is het caramel.
Unless it was sold as a creamsicle or the breeder is known to have worked with creamsicles, I wouldn't label it as such.
