Higher quality backgrounds for chromecast

Hey team,

I love and consistently use the chromecast integration that Roon has for outputting to a display.

However I often find that the background image is not of high enough quality to display on a TV screen. This just ends up making things look ugly.

While I don’t know where Roon sources these images, it would be great if Roon team could setup minimum image quality for anything that sits in that repository. I’m sure a big part of this is the repo wasn’t developed initially with tv screens in mind, so its key that the repo is updated. If on the other hand Roon pulls images from different repos for local vs streamed content, it would be good to unify the backgrounds to high quality content.
