Yuck: the misconception that GIF is lossless was common when JPEG just came out. You are right that recoding GIF's ad infinitum does not lose more and more information every time, but encoding to GIF for the first time loses 16 out of 24 bitplanes of information. GIF is a colormapped format accommodating at most 256 colors.
Well, sometimes there are no 24 bitplanes of information.
