(I guess that confirms that it can play MKVs too, I wasn't sure about that). This isn't a super primo set, it's an 'Entry Level' HDR UHD 65" screen but I could see a decent more amount of detail in the highlights and shadows, though that redwood video gets REAL crunchy in the blacks in both SDR or HDR.Thanks for testing. Samsung TVs when in HDR mode will change the backlight to 20 and contrast to 100. That is sort of the only way to check whether the TV is in HDR mode.
Of course, I'm assuming the TV wasn't doing something like converting the HDR to SDR and tone mapping it or something, TVs often give users next to no meaningful feedback on what it's ingesting. :X

My understanding was that the VP9 bitstream within WebM container already has the HDR metadata embedded. I don't know much about VP9 format. So, not sure where to look for the metadata.

Even then, those files would not play correctly in Kodi since Kodi (in combination with various OS'es) does not A) support HDMI injection of the required metadataYou may want to check how YouTube-dl script works and also take a look at the clip info I have pasted in the post above.

I expect LG to update the internal app accordingly...
Give it some time.

On another note, and slightly OT. I think it's a difference between real native support and "dump it into a hardware decoder and hope for the best" support.
Is the metadata buried in the container or video itself?
