That is indeed my current conclusion of the least-ethically-bad viable monetization. Purely cosmetic.
However, paid status is not really a big hook for single-player games, you need to be able to show it off! This means that the game must be designed primarily around multiplayer interaction, which is fine but limits a lot the kinds of games you can implement with this monetization.
