Hide UI in Campaign Theater?

Hey, is there any way to hide the “Skip” prompt that pops up when re-watching a cutscene in the Campaign/Theater section?

The only way I found to record cutscenes without any UI elements is by doing it inside the mission itself, however the second cutscene in the game plays in standard 16:9 instead of 21:9. Anyhow… I could use DSR but I was looking to avoid that.
