your test is nothing more than a comparison of your camera exporting into JPEG, and photoshop elements 6 exporting into JPEG
well in this very case I believe the actual file that Element 6 would send to the printer would be a TIF file which is about looseless compression.
But it is true that RAW data format tries to keep as close as possible to the output of the sensor. In particular the bayer matrix is kept, every pixel is green, red or blue.
