Hint: In general, even qualitative superiority doesn't automatically warrant a higher tier. In a group, the one in charge has qualitative superiority over the rest of the team, but that's just social, not dimensional. In real life, you don't see citizens claiming that politicians are universe level+, not even via social influencing. The qualitative superiority in question still needs to be in the context of physical dimensional transcendence for it to make a character qualify for a higher tier.
Maybe the Devourer's knowledge has qualitative superiority, meaning they possibly even qualify for the "Supergenius" intelligence rank given that the rank is portrayed as the one for characters with higher-dimensional intelligence, (even though I think that the VS Battles Wiki handles it questionably at the moment and one of my many plans is to revise it,) but if the Devourer's physical feat is going into cosmic background radiation and lurking in the computer that holds the simulation, that probably just means they scale above everything in the simulation without the context of qualitative superiority that the player has until the Devourer reaches the player's level. Also, remember, transcending an infinite multiverse doesn't qualify for tier 1 without the context of qualitative superiority. Have in mind that the the word "transcend" just means to go beyond the limits of something. Going "beyond the limits" of an infinite multiverse still could be anything below being inexpressibly infinitely beyond it. To "transcend" may or may not mean qualitative superiority.
