App Refresh After Screen Mirroring

Does anyone know if an app, when placed in Single App Mode, is refreshed before or after initiating a screen mirroring session?


The scenario is that we are looking to attempt to log the usage of our Apple TVs. By creating an image well in a hidden layer in our tvOS app, which we do put in Single App Mode via our MDM, we were hoping the app in Single App Mode would be refreshed after a screen mirroring session and we could log the GET from the app refresh. But nowhere can I find if apps refresh, especially in Single App Mode, before or after Screen Mirroring. I've read up on Silent Notifications and Background Fetch and that seems promising but that doesn't answer the me the Screen Mirroring scenario.
