Google TV Streamer AV1 Support

[Bobsled3]

I am starting to convert some of my larger 4K movies to AV1 only to discover that my LG TV will not directplay them as its quite a few years old. I am thinking of getting the new google tv streamer as it sates it has AV1 support. Are they any users on here that use jellyfin on one of these boxes with AV1 playback and will it directplay, and how do you find it?? Or do any users have any recommendations for a better media player box thats UK based

Thanks
