Quantum supremacy is a statement about about the asymptotic behavior of quantum and classical computers, and obviously, a finite set of data points cannot prove anything about asymptotes. What these experiments are doing are gathering evidence against the extended Church-Turing thesis - in the same way other experiments are used to gather evidence in favor of/against general relativity or some other physical theory. The proof of quantum supremacy within the framework of the currently accepted laws of physics (quantum theory), has to be a mathematical proof. Currently, we have no idea how to construct such a proof.
