There are reasons to not (entirely) agree with this.  Consider that 
applications which are not designed to display raster images may still 
want an accurate color appearance on the display.  It is not necessary 
to waste a lot of memory in order to display accurate color.  It is 
not clear that humans will notice the difference due to extra bits 
though.

Regardless, the TIFF file format stores 16bits per color component for 
colormapped images.
