What events in Google Calendar automatically get a background?

Question

Android

The new calendar from Google automatically adds a background image to some events, for example, a photo of the place specified in the event, or a picture with plates if the event is called "Dinner with Vasya". What other events get the background? Maybe there is a selection somewhere?
