Sometimes the result is subtle, other time not. I did this recently and noticed that the information data for the JPEG showed fewer colors each time it was saved. I also created a highly out of gamut JPEG in Photoshop, and the out of gamut information was set up to show in bright red. Each time i saved the file the amount of red diminished.
Someone's probably going to say that the "test" is bullshit and doesn't conform to scientific principles. I don't care - I'm just not going to continue opening and saving JPEGs.
