Taken from the other thread which seemed to get really off topic. How are the levels different to the White Balance? I always thought they were the same thing if not similar. And I know that its possible to alter the levels of any photo to get a "more correct" white. But once its a jpg, you're working on pixels with loss in them. With RAW mode, the idea is that its uncompressed, and you fiddle with the whtie balance/levels/histogram before it gets saved as another file format. Well, at least thats my understanding of it.
