Surely any program that supports ICC profiles will display the correct
colour for an image irrespective of the gamma setting of the monitor. This
whole 1.8 gamma - 2.2 gamma for Mac and PC stems from Photoshop 4 days,
where monitor calibration was almost non-existent.
The way I think of it is to visualise the workflow needed to display an
image on screen.
Image RGB -> Lab (what colour is the image) -> Monitor RGB (now display the
colour on my screen)
The image -> Lab conversion is the profile embedded on your image. This
absolutely defines the colour of the image. All you are then saying is
'display this colour on screen' Whether the monitor is calibrated to gamma
1.8, or 2.2 the original colour in the image is the same, so the image on
screen should be the same.
I make the choice of gamma to use when profiling on the type of monitor that
is being profiled. I want my software to do as little as possible to achieve
my calibration, so I choose a gamma setting that is close to how my monitor
naturally works. This is normally 1.8 for LCDs, and 2.2 for CRTs.
The choice will however have change how uncalibrated applications display
images.
