Yeah - Nikon uses some lossy compression for some of their RAW formats,
which doesn't translate that well into LJPEG compression. Sony is likely to
have similar situation. However, I do believe at least Sony has an option
to switch to lossless mode, which completely disables compression. As far
as I know most Nikons also have that option - in that case you are more
likely do see compression improvements.
