Blueberry

[Qarağan]

Hello. Last year I bought a potted blueberry bush. Since I had never seen blueberry plant before, I believed the seller. The leaves on the bush haven't fallen off all winter. Despite the fact that it snowed three times during the winter. I live in zone 8A. Since the blueberry is a deciduous shrub, I had doubts. I found out on the Internet that there are several evergreen types of blueberries. I'm confused. Can you help me identify this plant? Is it blueberry or not? Here are photos of this bush. Thanks.
