Samsung and Amazon have announced the HDR10+ open standard:
HDR10+ elevates the HDR10 open standard with the addition of Dynamic Tone Mapping. The current HDR10 standard utilizes static metadata that does not change during playback despite scene specific brightness levels. As a result, image quality may not be optimal in some scenes. For example, when a movie's overall color scheme is very bright but has a few scenes filmed in relatively dim lighting, those scenes will appear significantly darker than what was originally envisioned by the director.
HDR10+ incorporates dynamic metadata that allows a high dynamic range (HDR) TV to adjust brightness levels on a scene-by-scene or even frame-by-frame basis. With the ability to display outstanding contrast with detailed highlights and a richer range of colors, HDR10+ produces images that are much closer to the director's intent.
All of Samsung's 2017 UHD TVs, including its premium QLED TV lineup, support HDR10+. In the second half of this year, Samsung's 2016 UHD TVs will gain HDR10+ support through a firmware update.
This is in contrast to the closed Dolby Vision standard:
Dynamic metadata is a particularly important addition in HDR10+ as it closes the gap between the open HDR standard and the closed Dolby Vision spec, which had previously touted dynamic metadata as one of its main differentiators over the original HDR10 standard. (Although Dolby still leads the pack when it comes to the highest color and brightness requirements, at least for now.) And of course, I'd be remiss in noting that unfortunately, the addition of HDR10+ now marks the fifth major HDR standard vying for industry support, along with the original HDR10, Dolby Vision, HLG, and Advanced HDR, because clearly four different versions were not quite enough for anyone yet.

Don't worry the bay of re-releases will take care of that faster than you can grab your hands on a disc ;)

Amazon couldn't care less about discs. Their involvement obviously pertains to original streaming content they produced. So if you have an Amazon Prime account and the correct TV, you are ready to go.
HDR can be a major stylistic change so I doubt we will see too much old content remastered for HDR. It will be a bigger consideration for new content, especially where the benefits are clear (maybe fantasy stuff like Game of Thrones, or anything in a film noir style).

There may be some benefit for black & white stuff. But 4k is probably enough resolution to dither instead.

I'll guess the film Sin City [wikipedia.org] is a prime target for a HDR enhancement. Other candidates are Sky Captain and the World of Tomorrow [wikipedia.org], Casshern [wikipedia.org], Immortal [wikipedia.org] etc.
Btw, how many bits/s does Amazon Prime chew up?

BTW you have asked so many questions lately that you can just Google.
