What does this setting actually do? Just lower video quality? It's annoying it doesn't just tell you.

I'm on a MacBook Pro (16-inch, 2019) and I also see this checkbox. I didn't even think this model supports HDR.

Edit: Apparently, HDR is only supported on an external display. And if you connect an external display, it uses ATI* graphics. And you're probably going to want to connect the power adapter at that point. Which means that "Optimize video streaming while on battery" is pretty much a useless option on this model, unless it actually does other undocumented stuff.

* AMD ATI forever
