I got in IRC a small code snipet that allows full modification, it
inverts the colours so I think it should be possible to load any other
curve you can think of, if it is per channel.

Most monitors I have found were not 2.2. Only last one is 2.2, and
when sRGB preset. This "small detail" is what I think has caused lots
of problems, people knew their monitor was designed to be pluged in a
50Hz socket, or 60, or auto select among both, but not what colour
config was provided by it and the video card (and probably do not
understand it anyway).
