There's a lot to cover. HDR is coming to the web (and already exists on native) and there's certainly lots of issues doing it correctly, and, learning all of the various parts and how to deal with them. (HDR input data, HDR processing, HDR output, the display itself which may or may not be HDR and even if it is HDR might only have so much "headroom", etc..., and there are tradeoffs at each step.
Maybe not appropriate for that particular article but definitely appropriate for the site
Even native still has tons of issues, like the fact that AFAICT, no OS does HDR screen capture. You're viewing an HDR image, you ask the OS to capture the screen. It gives you an SDR capture :( On Mac and iOS that's certainly true. On Windows, the XBox Game Bar thingy will actually capture HDR but the OS level PrintScreen method will not, and the popular ShareX will not either.
