Is this supposed to be impressive? Dead Island 2 is a mid budget game with zero marketing that only got popular over time thanks to WoM, and Diablo 4 sells the bulk on PC, and had a digital edition that gave you early access (neither of those tracked by these charts).
In terms of direct comparisons, this game did worse than RE, SW, HL, and TOTK. It is the worst performing big budget debut of the year so far. You literally had to reach the bottom of the barrel and compare to dead island 2 to make these numbers seem good (you very conspicuously don’t mention the debuts of the other major games this year).
Hopefully digital makes up the difference because right now this is a TERRIBLE debut, and not at all making the point your damage control wants to make.
