Did it have auto temp controls, fog lights, heated seats ? If not, I'd assume it's just an es plus that the dealer put aluminum wheels on. I'm pretty sure all our 15' es plus' have vents under the front seats.

I assume the convienience package is es plus? I didn't know that included cruise, thought that was standard in an se? Cruise didn't come in an es plus in 15 or 17' but did it 19'.
Maybe 14' was a weird year?
