That means there is a bug in the display code then, because lcms uses
CIELab (the FAQ comfirms it http://www.littlecms.com/faq.htm).
And in CIELab (as shown here http://en.wikipedia.org/wiki/CIELAB) a*
and b* are signed. As opposed to ICCLab (mostly used in tiff files)
where a* and b* are translated to be unsigned. But I will wait for
Adrian answer :)
