Does sRGB also support showing color in full range? My question is that, now sometime the image showing in the canvas would be different from what a video frame actually looks like, where video shows in full range of color, the image captured from canvas only showw in limited range of color. If this is the fact of how current reftest framework works, does that means we can't use reftest to check full range of color? because in some cases it couldn't reflect the actual video frame, if the video is showing in the device color space, which is not sRGB. If that is the fact that we couldn't change, how would we compare full range of color well on those cases? Now I encounter a [case](https://phabricator.services.mozilla.com/D134352#4389515) in the try-server (only on Windows R-sw) which I think shouldn't be a blocker for landing my change for ffmpeg, if this problem exists prior my patches. Thank you.
