What kind of blue shrimp did I get?

[Nicnet]

Hey all! I decided to start a tank just for shrimp. I got it all set up with black sand and live plants, and went to a highly recommended new store for some shrimp. I fell in love with Blue Tiger shrimp, but seeing them as 4 for $99.00 online was ridiculous, so I figured blue shrimp were just a dream... Until I saw my babies!! I'm not sure what kind they are, since I've read mixed opinions online, but I'm pretty sure they aren't the blue tiger shrimp, although some do have the orange eyes! They aren't the snowballs either, seeing as they are a dark vibrant blue, not just a really soft barely visible blue.

Here are some pictures of my babies!!

Hmm I just feel like my shrimp are so much darker than the blue pearls... But I'll look into it.
