The cake is certainly buttercream. Looks like they had the cake in the refrigerator OR freezer for a few moments and the darker shade appears to be what the buttercream looks like when cold/frozen. The lighter shade looks to be the buttercream at room temp. I have had this happen numerous times with the darker colors such as purple, orange, navy blue, and dark green. The cake is iced completely smooth, most likely using an icing that does NOT crust and placing the cake in/out the freezer or fridge to allow the butter to solidify, then you can smooth the icing. When you do this, the icing does tend to discolor a little, but creates the velvet look.
