[gentoo-user] CMYK comparison to sRGB between platforms

[Mick]

On the same hardware I noticed that a CMYK photograph converted to sRGB looked 
mostly the same (indistinguishable) on Linux, but the sRGB colours were 
brighter on MSWindows.

I tried this by dual booting between MSWindows and Linux.

Then I tried it by running MSWindows within a VM on a Linux host and the 
MSWindows showed a clear difference in brightness between the two formats.

Finally, I checked on an AppleMac and the difference between the CMYK and sRGB 
photographs was even more prominent than MSWindows.

So, the Linux renedering seems to be misleading the user.  Have you noticed 
the same?

BTW, both Linux machines that I tried this on are running radeon drivers - are 
these to blame?  The AppleMac is running Intel graphics with its 'retina' 
monitor.  Is it a matter of somehow tuning the Xorg settings on my Linux PCs?
