jpeg and internal jpeg differences

Some years ago, just out of interest, I loaded a large fine jpeg, and the internal jpeg (extracted with the 'Instant Jpeg from Raw' app) into two layers in Photoshop, and set the blend mode to difference. I found I had to do an awful lot of lifting of the black image you get before you see the differences. I'm not sure I can see the degradation in an internal large basic jpeg especially without anything to compare it to, let alone my relatives looking at images on a computer screen.

This was with a D80, the internal jpeg processing in other cameras may be different, try it and see what you think, you may be surprised.
