Issue: Exported video color profile showing as HD (1-1-1) instead of selected sRGB.

Video files quite generally don't use any color profiles except for intermediate workflows, i.e. exchanging clips between programs that support color management by assigning profiles in the footage interpretation or metadata. The rest doesn't matter. Matching video to a page background has nothing to do with actual CM and is ultimately a futile exercise. There will always be a browser or mobile device that doesn't render the page as designed since they don't have any CM and are tied to a terrible display color profile. The rest is just a matter of understanding how web pages are rendered in the general sense, how compression affects color and somewhere inbetween finding a way of reducing these problems with color management and eyeballing adjustments to compensate for these deviations. So for what it's worth, whatever you are trying to see there is probably just the default stream info as interpreted by OS X when no CM is present and bears zero relevance. Every web video designer would be happy to just slap on a color profile and enforce correct colors, but that's unfortunately not how things work. If you have specific problems, you need to provide some actual info about your project, how the video is integrated, screenshots illustrating any potential color discrepancies and so on.
