The source files are exr which are 32bit (or 16bit at worst, but standard exr is 32bit) thus you can safely grade/master them to 10 HDR, even 12bit if you want. There's plenty of dynamic range/headroom.

I looked into this a few years back. While we have lots of precision in the source, it was all graded and rendered for 709 SDR. One could probably use those assets to remaster it to HDR, but that would require regrading, rerendering the CGI stuff, and recompositing. Feasible, certainly, and a lot less work than doing a project from scratch. But still a sizable effort to make it look like "Real" HDR, and that's even assuming they did the RAW acquisition preserving the highlights and such.
I've been involved in a number of HDR remastering projects, and doing it well is quite a lot of effort. Particularly for something as CGI-centric as Tears of Steel.
