I played around with both the blu-ray and 4K blu-ray, and the 10 bit color of the HDR version definitely has more information that can be recovered, of course it is more demanding on a computer to work with and you have to deal with the HDR to SDR tonemapping as well.
Definitely though this movie needs scene by scene or even shot by shot adjustments to make it look more normal, which The Bold One definitely does even if over the top.
