I expect that you will be able to see one today (CPU is crunching to generate the huge colormap). In the mean time, I am interested to know who is able to load and view the *beautiful* 4096 color (12-bits per sample) colormapped TIFF file I have made available at: ftp://ftp.graphicsmagick.org/pub/outgoing/colormapped-12-bit.tiff The current GraphicsMagick 1.2 development snapshot is able to read and write this file just fine.
