The code is based on Jack's but implemented quite differently.

I don't think so...

I just ripped Audacity's dither code and put it in a simple
jack app to test it. Things seem OK... The 'shaped' spectrum
is not entirely what I expected, but it's quite different and
*way* lower than what I measused on you files.

There must be something else going on...
