That's not how HDR works. It expands the high range exclusively. So more like 0 to 1000 instead of 0 to 100.

You're right about how HDR should work. I'm reporting how my Samsung TV does work. It's terrible, and clearly a bug. There are many, many forum posts about "samsung hdr dark", often with random advice about adjusting the gamma, etc., that sounds like it should work but only helps a little bit.

Your approximation isn't really better than theirs.

It's true that you can't go below black, but SDR has extremely bad precision below 1 nit. HDR can accurately represent scenes at least 100x darker than SDR, in addition to bright spots at least 100x brighter. https://2.img-dpreview.com/files/p/TS940x940~forums/66687985...
