Something else to mention is that, as usual, TV manufacturers are being a little creative with their specifications when it comes to the nits output of their HDR TVs.

The current luminance king, the Samsung KS9500 for example is rated at 1400 candelas, but that is only at 10% of the screen having maximum white, it drops off to 500 candelas at 100% white.

You can see how the current models fare here:

Broadcast HDR monitors are still crazily expensive, I think the Sony is the cheapest at around $42,000 Australian Dollarydoos, for their BVM-X300 30" monitor. Hopefull FSI will come up with something more affordable.
