I suppose you could argue that it’s a logical and inescapable consequence of MWI
It is. If you believe MWI, you believe that Schrodinger’s cat will experience survival every time, even if you repeated the experiment 100 times, but that you will observe the cat dead if you repeat the experiment enough times.
There is no falsifiable fact above and beyond MWI as far as I can see, apart from the general air of confusion about subjective experience, which hasn’t coalesced into anything sufficiently definite enough to be falsified.
