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

Correct. Makes it easier on the decoders. Though I'm not sure how much of a difference it actually makes.
Edit: Just realized my answer may be misleading. I don't think it affects bitrate. It applies to HDR content.
As @bsamcash mentioned, this setting influences hdr content. Specifically :
While on battery power, play high-dynamic-range (HDR) video in standard dynamic range (SDR), which requires less energy. See the Apple Support article Play HDR video on your Mac

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.
