Terry, I regularly use pdfimages to losslessly extract images from PDF files and and the convert these PBMs to TIFFs or GIFs with ImageMagick. Although using various versions of IM, I have never encountered any problems with that. I have just tried to use PNG instead of GIF and have met no problems with doing so.
Considering your PDF: Extracting the images with pdfimages, I get the same results as you. But I meet no problems when converting them to PNGs; they look just the same as the originals. BTW: PNG does a much better job on compression than TIFF (and even GIF), so perhaps I should switch to PNG in the future... At the moment I'm using ImageMagick 6.6.3-0 2010-07-01 Q16 on Windows XP and Windows 7, 32 bit. Perhaps this is a problem with the very IM version you use, check with http://www.imagemagick.org/script/changelog.php.
