The iOS client displays HDR videos darker than expected.

The HDR brightness on the iOS client is relatively dim, and it seems that the HDR brightness of the screen is not activated

The video file I used is in an MKV container, and the video format is 4K DV. I noticed that when playing this video on the client, the brightness is darker than when playing it in the browser.

During testing, I found that when playing in the browser, Emby converted the container (I’m not sure exactly what, but I think it’s MOV/MP4), whereas the client did not. However, I don’t think this is the reason, because the screenshots hardly show any difference, as the two images seem the same in an SDR environment.

I haven’t tested how the same video in an MP4 container performs on the client.

I hope someone can provide an explanation, thank you.

Hi, yes this would be a useful test using the same video. Thanks !
