If you keep looking at examples, you will learn the differences.
In my personal opinion, I think quality examples look totally different.
They have different colors and patterns.
One of the main black pastel traits are the squiggles in their alien head pattern.
Cinnies are more reddish brown in hue.

Black Pastel:


Cinnamon:

If I can't tell at first glance if a snake is black pastel or cinnamon, then it's not good enough to be in my collection. When you have good examples of the two morphs (like pictured above), then it's very obvious that there is a huge difference. When they are poor quality, then you will have a harder time telling them apart.
