Ryan here is a photo of a mature rosette of 'Pacific Blue Ice' showing the same basic colors. Yours will look a little different because it is small, has been shipped, treated for pests and finally into soil. But I do think you have the correct plant.
Mealy bug can get into a nursery easily and become a real problem. The nursery people here treat for it whether the see them or not, just as a precautionary thing.
That is why I like to buy my semps bare root. All soil cleaned off and roots dried out before shipping.
