It is gamma.

Most PCs still use uncorrected gamma to my knowledge, so yes, it's still a
consideration. If you're designing on a Mac, you can change your monitor
gamma temporarily to preview, via the Monitors & Sound control panel. (I
think there's also a control strip module floating around that will do it
in one click.)

Not sure whether there's an easy way in Windows to switch gamma values.

The PNG format has the ability to store a gamma value, but that doesn't
help if you're using GIF or JPEG.
