Difference Between Silver Streak and Sterling Pastel

[LGL]

Hey! I've seen many people use "Silver Streak" for a Super Pastel Cinny "Sterling Pastel" for a Super Pastel Cinny. From what I've seen, though, Silver Streaks and Sterlings look different. So I was wondering, is there a difference between them? Are they two different lines (like are they Cinny and Black Pastel) or what? Thanks!

I believe that the silver streak is the super pastel black pastel, and the Sterling Pastel is the super pastel cinny.
