Maximality of those traits? I don’t think that’s empirically determinable at all, and certainly not practically measurable by humans.
One can certainly have beliefs about comparative levels of power, knowledge, and benevolence. The types of evidence for and against them should be pretty obvious under most circumstances. Evidence against those traits being greater than some particular standard is also evidence against maximality of those traits. However, evidence for reaching some particular standard is only evidence for maximality if you already believe that the standard in question is the highest that can possibly exist.
I don’t see any reason why we should believe that any standard that we can empirically determine is maximal, so I don’t think that one can rationally believe some entity to be maximal in any such trait. At best, we can have evidence that they are far beyond human capability.
