That said, like you, this is pretty much exclusively HDR content that's TV shows, as opposed to movies; where for movies it's always disc
Weren't the Panasonic players condemned to 60FPS hell for streamed content? Or have they fixed that? That would be a big shame if you had to go to 60FPS with 3:2 to get colour/ luminance that works.

If the video is supplied with DV metadata then it may or may not be possible to calculate correct HDR10 metadata from the DV data. Especially HDR10 metadata that matches what the original master for blu-ray intended.
This problem is only going to get worse because more and more flat panel TVs are going to support DV. This may lead to the death of HDR10 metadata for streaming devices if they quit supplying HDR10 metadata.
It may be like the betamax / VHS wars. As a result, for streaming, DV may win and HDR10 just won't be available except on UHD blu-ray disc where it is required. Unless that changes over time as well.
I think it is "only" on AppleTV that DV has managed to really get a stranglehold, isn't it? Plently of other platforms stream in HDR10.
The Sony UBX800 UHD player does netflix HDR10 but it annoys me because it switches framerates during the previews which renders the UI almost unusable on a JVC with long sync times.
I'm not sure if I've said this in this thread or another, but there is nothing at all difficult about calculating MaxFALL and MaxCLL. The pseudocode algorithm is less than a page of A4 for both in the CEA spec. All that is stopping this being done properly is the will to do it (as Apple could clearly (if they wanted to) play the stream through the DV -> HDR10 conversion and pump the resulting frames into the algorithm, then store and retrieve at playback time the correct data.
There is much more to it than this though. There is a fair bit of content which works OK, which leads me to think DV converted could work fine, the problem is that there is either someone somewhere applying the wrong settings, or there is some version of encoder packs which creates broken streams. That Daredevil S1&2 are broken, yet S3 is fine, with all three being DV, says there are probably just monkeys at the wheels somewhere (either writing or driving the software).
