You'll be happy to hear that we've recently dramatically improved the audio quality of sped up (and slowed down) videos, here is the ticket for the details: https://bugzilla.mozilla.org/show_bug.cgi?id=1427267 https://bugzilla.mozilla.org/show_bug.cgi?id=1427267. This will be release in Firefox 73, in about 4 weeks (give or take a few days maybe). HDR is very much in the list of things we want to do (especially for videos), but as you can imagine, it's not particularly trivial, and will require platform specific work, and deep changes into Firefox. On the other hand, hardware is shipping (we got some devices so that developers can start assessing the situation), and HDR content is becoming increasingly available, so we're trying to figure out what it will take to do it properly.
