Show source when top left pixel is a specific colour.

In my church we use WorshipTools.com Presenter to present lyrics and slides etc. live to the congregation. There is an option to output a secondary display which we have configured with a chroma key to display the song lyrics over a camera feed.

Unfortunately, there is no way to only output lyrics, so for example a song is finished and we display a full screen notice slide, this covers the camera feed. We only want the source to show when there are lyrics, so I was thinking that maybe there was some way to show the source only if the top left pixel is set to the chroma key colour.

Is there a way to do this?
