That helps already.

As you manipulate the image by adding the watermark, the image will have to 
be recompressed on saving. And like was said in a similar thread, a PC has 
more power than a camera, so it might do a better job at compressing w/o 
degradation.

Also, looking at the images you  provided, I don't see any degradation. So 
if you agree on that point, there seems to be no problem. Unless, perhaps, 
when you have to do more editing on the images (but then why put the 
watermark already...)
