Are fresh shrimp tails as easy to peel as the ones I get from the grocery store?

Factual Questions
1

Every now and then I buy shrimp tails from the grocery store. Although they are tedious to peel, surprisingly little physical force is required. The large segments on top of the tail are thin, flexible, and separate relatively easy, the swimmerets on the underside of the tail can be pretty much wiped away with a swipe of the index finger.

If I catch a live shrimp, will the tail be as easy to peel (once I’ve killed the shrimp and severed the tail from the rest of the body)? Or has time-since-death (and a freeze-thaw cycle) made the store-bought shrimp easier to peel?

In my experience they are easier to peel because the legs are more strongly attached to the shell. They are still harder to peel then the deveined shrimp though.
