The described Canon format would have better quantization than a typical
camera JPEG., but isn't a truly "raw" format. The CCD or CMOS sensor in
the camera doesn't have its primaries in the same spatial location, so
any transformation to a format that does, such as JPEG, is lossy.
The Canon cameras I have used give a raw format that is entirely
unrelated to JPEG.
