Latest What HI FI say's this,
All of Samsung’s 2017 4K TVs have HDR10+ support built in, while a firmware update will make it available to existing 2016 4K TVs. Predictably, the company's 2018 line-up of TVs will support the format, too.
And also this about HLG,
Hybrid Log Gamma (HLG) is potentially the most important HDR format of all. Why? Because it's going to be used with TV broadcasts.
The result of a joint research project between the BBC and Japanese broadcaster NHK, HLG is designed to deliver a more convenient HDR solution for the broadcast world.
It takes standard dynamic range and high dynamic range images and combines them into one feed, with HLG-compatible 4K TVs able to decode and show HDR images in all their glory.
Most big-name manufacturers confirmed HLG-ready sets for 2017, with Samsung, Sony and LG also announcing that their 2016 HDR TVs will receive HLG support via a firmware update. Panasonic is also offering the same for select top-tier 2016 models, too. With the framework in place, all we needed was some content...
And it came in the form of Blue Planet II - released in full 4K and HLG on BBC iPlayer for just 30 days in late 2017 (it expired mid-January 2018). While BBC had previously shown a clip of Planet Earth II in 4K HLG, the full series release of seven-episode Blue Planet II showed that HLG not only worked, but it looks spectacular.
The only potential issues are the different variations of HDR and the need to ensure your TV is future-proofed for when the different versions go mainstream. At the moment, we'd ensure yours has HDR10 and Hybrid Log Gamma as the bare minimum. We were hoping the situation would become more stable by CES 2018, but it seems there's a bubbling format war between HDR10+ vs Dolby Vision.
Seems Samsung have not updated What HI FI, and if anyone is in contact with What Hi Fi it might be useful to have a word.
