  Given that sRGB is a much smaller gamut than L*a*b ... It wouldn't be much
more difficult to convert from one of the larger gamut color spaces ...
e.g., ProPhoto.  Granted, there are few devices that can take advantage of
large gamut color spaces, but sRGB (... A de facto monitor standard ...)
seems too small to be worthy of a conversion to L*a*b.

  ... Just a suggestion ...
