1. On 27" screen size, I doubt you would have a sharpness/detail benefit in comparison to 1440p. Especially in online video.
2. I do not see any mention of HDR support. Apparently it’s a 10-bit monitor, but that does not imply it’s HDR capable.
3. I would not know nearly enough about calibration to tell you about this.
   4 More pixels per inch (or per cm, whatever) often mean that e.g. text gets smaller. One of the many reasons I believe in the idea that 2160p screens only make sense (in some scenarios) when they are larger than 27". Otherwise you may start needing scaling even when your eyesight is better than mine.
4. No idea about brightness specs like that, so I won’t comment on that.
5. That is normal with a lot of monitors out there.

The link you posted is broken because it seems to miss the “y” at the end. It should be: https://www.linuxfoundation.org/about/inclusion-accessibility

Indeed, it would have been a lot funnier without the caption.

I switched to it (KDE version) earlier this year (away from Fedora) and apart from a few minor things (e.g. there was no firewall, so I installed firewalld) it has been running pretty well.
