SmartTV Sonos Sound Bar App

I have a question about the Sonos Sound Bar app on my Smart TV. (My Sonos app on mobile phone works as expected and enables me to control all my audio settings. My question does not relate to the sonos app on my mobile phone).

 

As part of setting up my sonos arc ultra and sub gen 4 with my smart TV, a mysterious "Sonos Sound Bar" app has appeared on my SmartTV. This app is grey with a white speaker image on it. Clicking on the app reveals no functionality at all: all I am shown is a series of weird black and white lines on the screen. The images look semi artistic and look like attempts to draw different types of sound waves. The images change every few seconds. But other than this, the app does nothing. And I am unable to delete it from my SmartTV

 

Does anyone else have the same experience? What is this app for? It seems completely superfluous and bizarre.

It's not an app.  It's a source indicator, allowing you to switch to the HDMI that the Arc Ultra is connected to.  Not really useful, because the only thing being transmitted by the Arc Ultra is that pattern of lines.

    Since some TVs show the eARC connection used to send sound to your Sonos, they added the pattern as a Screensaver so the TV doesn't damage the display.

    Many TVs will let you hide the eARC Input which is convenient since all it ever shows is the screensaver pattern.
