In my honest opinion related to this discussion is that the watermark should be visible only when you open the leaderboard or the menu, like the name display for the mods.
Im aware that the watermark does make plutonium more visible to other people but in my opinion plutonium became the BASE launcher to play black ops 2 or other famous golden era cod games
So making that change would not only be less intrusive for those players with lower screen resolutions (and some others with ocd) or those that try to use the theater mode, but wouldnt affect the visibility of the launcher that much since the launcher already has become famous and not because of the watermark
