If you have one of Samsung's latter-day QLED or UHD high-end TVs like the Samsung Q9F, you're in for a treat. As of today,  you can stream in HDR10+ now on the units through Amazon Prime Video. 

Samsung claimed in a press release that it's the first time this kind of quality has been achieved through streaming alone. Netflix told us just two days ago that there's a "possibility" the same HDR10+ support could come to its own service, but the vague nature of the response likely means that kind of support is still far in the future.
