I have one and use it outside regularly (e.g. [0]), it's pretty amazing!
There's some open-source tooling[1] for it which can control screen features like brightness/refreshes/rendering modes/... and I've set it up[2] to work with my unprivileged user so that I can bind these features to keys in my Emacs.
With these screens you want to use light themes, and use tooling to improve contrast on websites (a friend wrote a Firefox extension[3] which is amazing for this).
