Dolby Vision displaying HDR logo?

I believe this may have been mentioned before. When I stream DV 4K mp4s using Plex onto my Shield my LG CX displays an HDR logo instead of the Dolby Vision logo. Is this normal? The content plays fine I’m just unsure it’s utilising DV.
Thanks

What model Shield do you have?

Shield TV Pro 2019

Did you enable it in the global Shield settings? DoVi works with other apps such as Netflix of Disney+?

It works perfectly with Netflix, Disney + and Apple TV

Are you on 8.11 public or 8.12 beta release?

8.11. Not sure how to get the beta. Can I get it via an APK? I have a Plex pass. Should I be on the beta?

Can you DM me the metadata/mediainfo?

Sure. I’m not entirely sure what you mean the metadata of the DoVi file?

From Get Info in Plex Web app on the title

Sure. Do you want the XML or a screen shot of the info?

The file looks correct. Its something else.

Any ideas what? DoVi plays perfectly through everything else. I’m upgrading my home networking this week and putting in a Synology 920+ so can have another go with that. Not that should change anything. No matter how many times I restart the file it still won’t acknowledge it’s DoVi.

Any ideas where the problem lies so I can take a look how to potentially fix it? Thanks

Look into the logs of the Plex app on the Shield

Thanks. Can you point me in the direction of how to do that please?

Thanks. I have dm’ed you those logs. I have no idea what I’m looking at/for so I’m hoping you might be able to help. Many thanks.

Would you be able to create a sample of the video that fails and we can take a look.

Information about creating a sample is available here: https://support.plex.tv/articles/201035968-generating-sample-files-from-media/

I can do yes, give me a couple of days thanks. I know have the Atmos error too which I’ll post about separately
