small nitpicks on your nitpick, but
- orange peel refers to any paint layer, not just clearcoat. (almost all, if not all, cars today are shot with at least 2 stage, but older and maybe some cars may be a single paint coat, where orange peel can still be exhibited).
- it's not from spraying it improperly, which can be a cause, but more typically that the spraying conditions (from paint mix to atmospheric conditions, even inside a booth) aren't "ideal". most new cars are robot sprayed with perfect spray control, and almost all new cars exhibit a small degree of orange peel.
even ferraris have orange peel from the factory. this is why high dollar detailers do a "paint correction" as part of their work, even on a brand new car.
