I imagine people have multiple screens but don’t want to keep multiple copies of a video?

In this case I would think people would prefer to just have the SDR version which will look good on all displays rather than the HDR version that will look better on a HDR display but will look horrible on a SDR display. It's down to personal preference of course, but I can't imagine someone caring about having HDR videos while simultaneously putting up with the bad results of automatic HDR-to-SDR.

Just as an example since I didn't include one before: Which of the two below images using different algorithms is correctly tone-mapped? Do we care more about showing the details of the car and the driver or do we care more about the rest of the scene? It's simply not possible to decide which of these is better without context, which an algorithm will never have. A human watching the scene can make that decision, or pick something completely different.

Why are you so consistently telling other people what their preferences should be and why?

As I said already, it's down to personal preference. I just don't imagine that most people care about having the best looking video they can get on one device but don't care on another to the point where they'd sacrifice quality on device A for better quality on device B.

It’s exactly the case. Every room isn’t a home theater. We want the best quality for the home theater and “good enough” for the rest. To my surprise, others do notice the washed out effect of watching HDR content on an SDR TV, or worse the wrong colors when watching DV content on an SDR TV.

Acquiring, storing, and organizing multiple files for the same video is a hassle. Even more hassle is asking others to know which is the right one for that TV.

Nope. I personally have two HDR devices and two non-HDR ones. I don't want to keep two separate copies as this takes up more storage, requires me to get two different versions whcih means the progress won't be synced ebtweent the two, the subtitles may not be exactly the same either, etc.

I want to have one and only file that will optimally on my main device (HDR) but which also work reasonably well on a secondary non-HDR device.

Ideally Jellyfin would handle the latter two points (and I think it does), but the first two are good reasons.
