HDR monitor do exist. BrightSide Technologies was showing them at SIGGRAPH over ten years ago. Looks like consumer OLEDs are starting to get on board [1]. And, they did really want 10 bits per channel. But, even that seems lightweight.

10 bits per channel will carry us for a while. Apparently Dolby bought BrightSide and now they are pushing for 12 bits. 16 bit ints will probably be enough for home use in practice. Internally, most games that do HDR rendering use 16 bit floats for their intermediate frame buffers. That format is popular in film production as well. I would be surprised if consumer display tech ever bothered to go float16-over-DVI. But, maybe it will get cheap enough eventually that we might as well have the best :)
