Well, if we're getting into semantics we could maybe say cooked vs prepared, I'm not sure. There's obvious physical differences between burnt onions and caramelized onions. Similarly, there's obvious physical differences between scorched, dry, but safe to eat chicken, and chicken that has been prepared properly and is tender and juicy. In the context of this thread, we've been talking about cooking things as part of recipes, so the end result and quality is obviously important.
