Philips OLED809 chooses HDR10+ instead of Dolby Vision in Emby

[yzxvw 19]

Hi, I’m having an issue with Dolby Vision playback on a Philips OLED809 Google TV.

Some of my files contain both Dolby Vision and HDR10+ metadata. When I play them through Emby on the Philips TV, the TV always switches to HDR10+ / HDR10+ Adaptive instead of Dolby Vision.

I tested the same files with Emby on two different TCL TVs, and they trigger Dolby Vision correctly there. So I’m not sure if this is an Emby issue, a Philips Android/Google TV issue, or just how this TV reports/handles HDR capabilities.

The files are Direct Play, not transcoding. Is there any way in Emby to prefer Dolby Vision over HDR10+ on this device, or is this controlled entirely by the TV/system player?

Happy to provide logs if needed. But I think it's more like a client side issue so I don't think the server log could help much.
