  Actually that's exactly what gamma correction data in the images is
trying to fix: To actually make the image look the same when you switch to
a different monitor technology (assuming you configure your system gamma
settings properly). That's the whole idea of gamma information.

  (Of course how well this will succeed in practice depends on a ton of
things. It requires for the OS to have a proper gamma correction setting
in its display device driver, among other things.)

  Actually a full post-processing scripting language would be nice, and
many times discussed, but ton of work to design properly.
