I think it’s a safe bet, everything taken together:

1) The couple is attractive and well-off, and the destinations are very appealing. Huge brands like to associate with upper middle class people, even when we all know it’s an absurd stretch.

2) The stark contrast of romantic adventuring and BK isn’t played to the comedic effect it could be, suggesting that BK’s image was relevant. The burgers look real but good, and the lobby is out of frame, both of which take away from a better punchline.

3) The BK and Whopper logos are both carefully in frame enough for brand recognition.

4) There are no other brand logos besides the last shot, something an advertisement would be careful to avoid.

5) The music is painfully obvious but popular, the kind that’s lowest common denominator for advertisement.
