Does not need to, but the whole variety is usually highest quality because the producer cannot hide the defects. Think about tea or tomatoes: the more you grind it down, the more you can mix in lower quality tiers. One exception I know of is porcini mushrooms: the most expensive are whole halfs, because you can actually see there's no worms in it. Also for mushrooms dried is really good, but obviously the texture is a little bit different when you eat it.
