Has anyone noticed that Apple's default "sRGB Profile.icc" supplied
with OS X (in /System/Library/ColorSync/Profiles) appears to have
the wrong tone response curves?

I compared it with sRGB profiles from various other sources, and
while the others all had TRCs represented as tables with 1024 entries,
containing what looked more or less like the linear-gamma function
in the specification, the Apple profile had TRCs described as
"gamma 2.199", not to mention different info the copyright and
description tags other missing information.
