Yeah, I got taken in by the 1000 vs 500 nits thing. I was expecting this display to be brighter (which would be great for use in bright environments), but, no, it's the same as my old mb pro. Way faster tho!
Now I wonder, can the NITS unlocked by HDR content be controlled in some way? Can I write an HDR terminal emulator? I want to be able to use neovim outside without issues.
I think it would be a fun hack to try.
otoh maybe it's something like only a small portion at once of the screen can be mega-bright, in which case the terminal emulator idea isn't going to work out. (though maybe you could super-bright an area around the current line, which would be better than nothing...)
(all of the above pure speculation, obviously)
