[BUG] Desktop player for macOS doesn't seamlessly integrate with the color scheme

Plex player for desktop doesn’t seamlessly render the window controls, showing this ugly gray window header, whereas other players, like Spotify, do seamlessly integrate with the window manager of macOS.

I don’t use Spotify or Mac as a daily driver so correct me where I’m wrong but it does appear that we do follow with the host OS’s Appearance setting. I have VLC, Spotify, and our Desktop app up. When selecting the Light and Dark themes, only our app is changing to match the selected appearance. VLC has it’s own app settings for handing it’s appearance and it appears that Spotify doesn’t have that and is set to a default black.

@Atomatth thanks for looking into this. So here’s the screenshot with the light theme to explain the UX discrepancy:
