Spotify on display

I often see here photos of the display where a flac file is played from NAS or so and cover art can be seen all over the display. The cover can be seen on the left side, but also visible behind the text. When I play via spotify connect the only thing I see is the cover on the left side, but nothing behind the text. Is that a specific setting or is that a difference between spotify connect and playing from another source like NAS ?

I guess they are using Roon
With hifi rose radio there also is nothing displayed behind the text but when using Roon radio there is

Currently, we do not support Spotify as an inapp, so album covers or Trek information cannot be loaded when connecting to Spotify. For example, just as it is the same when connecting your phone and Rose device via Bluetooth, it is the same with Spotify.

Thanks for your explanation
