There are for Windows, too. I don't know about Linux. The catch is that for really exact color work, you have to calibrate and tune for your computer/OS/video card/monitor combination, and check the calibration against a known standard periodically. It's a bit of pain.

Well this is pretty easy to test. Use a wide-gamut display and use the display's profile. Yeah, sure that might not be accurate, but it tells color-managed applications what the display color space roughly is. Then play a video. Observe whether the colors are drastically different from no profile and sRGB emulation in the display. In a color managed system, both of these should look roughly the same (and they do).

My result: Yes, they are. Totally different. Crab people everywhere. Player does not matter.
