Hi,

Video player plugin is not supporting HDR videos. When you try to play HDR video, it plays like SDR and different color.
You can try it video_player plugin's example, simply try to play any HDR video, you will notice different color video.

Video Player is top of AVPlayer and AVPlayer should play HDR videos automatically, but it didn't. I tried everything to find a workaround but no luck. Maybe https://developer.apple.com/news/?id=rwbholxw this helps.

Thanks,
