What does it tell? Your comment seems weirdly cynical, but maybe that's my reading?

I mean, one of the uses is the statement "Its variable aperture is a particular strength, significantly improving the camera’s ability to maintain sharpness in complex scenes and when multiple subjects are present.".

DXOMark is a technical test with generally little narrative, so I'm not sure what your point even is. Would it surprise you that their reviews of SLR lenses, where the aperture is a critical element of the lens (and it would be a joke not to have one), they generally don't mention it at all?
