> A hilarious example of this is seeing Microsoft use Macs to design UIs for Windows which then look too light because taking the same image file across to a PC shifts the brightness curve. Oops.
(Showing my age I’m sure) I distinctly remember how frustrating this was in the bad old days before widespread browser support for PNG [with alpha channel]. IIRC, that was typically caused by differences in the default white point. I could’ve sworn at some point Apple relented on that, eliminating most of the cross platform problems of the time. But then, everything was converging on sRGB.
I think you're thinking about gamma correction. Before 2009, Apple used a display gamma of 1.8, so images displayed differently than they did on Windows systems (which used a gamma of 2.2).
