How to get DolbyVision on WebOS??

[Host-in-the-Shell]

From what I understand, LG TVs do not support DV 7 (at least recent models don't). I have two and neither can play it back, always requiring transcoding; since Jellyfin can't do HDR to HDR transcode, it tonemaps to SDR. Historically LG TVs have had not great support for DV altogether, and I believe profile 7 was never implemented all that well. Most new models have support for 5 and 8, but 7 is possible only on an mp4 container and without support for lossless audio on some select older models. Even 8 still requires an mp4 contrainer for newer televisions.
