Arman, Apple doesn't give refurbished products when you get it replaced in a retail store. Instead, it's "Remanufactured". No components were used by someone, and it was tested individually versus in batch testing like you'd get with regular manufacturing. The reason it becomes "remanufactured" is because it failed during the first manufacturing process (taptic engine, battery, display, etc), and that component is replaced and then it is retested.
If you went to a carrier store or used an insurance like Asurion, you'll get a refurbished device - steer clear of that garbage.
