Auto tone mapping

[jdsizzlestix 0]

I feel like this subject has been touched on so many time but i cant find an actual answer to it. I can force tone mapping by forcing transcoding, but for some reason Emby will not detect a non hdr device and auto tone map. Tried this today on a apple tv, set to 4k SDR and played my hdr content. All i was getting was direct play, no tone mapping at all. Really frusterating
