Wouldn't you still be as sluggish as the GUIs you mention since it's HTML5? Is the benefit from only rendering a subset or something? I'm struggling understanding how rendering a page into a terminal is faster than just rendering to a regular window. It just seems like another layer between the browser and the GPU.

I think you have a misunderstanding of the full system. Like you are thinking the GUI is much simpler than it actually is. Conversely I think you're thinking that CLIs are much more complicated. There's a lot more going on than just painting pixels on the screen. Maybe start by asking why vim is several magnitudes less resource intensive then Microsoft word. Then ask the same about neomutt vs Thunderbird vs outlook/Apple Mail

I'm also not sure why you think it's an extra layer between the gpu. Both the browser and terminal emulator are sitting in top of the OS. But also remember if you run headless then your OS doesn't need to load the desktop environment, though you can still use the CLI. At this point clearly the GPU is seeing less, right?

I understand that a GUI is complex, which is why I'm confused about the performance benefit as HTML5 already acts like a GUI. Even if it's a terminal program, it would still need to calculate the layout and handle the DOM to remain compliant, no? A website can be as intensive as Word.

My logic with it being an additional layer is that instead of the browser rendering text to the screen, it would have to speak with the terminal for the terminal to instead render text to the screen. Same goes for rendering graphics. Besides a headless system I don't see much of a benefit to it.
