I was impressed with it too...but there are some out there who aren't.
Not sure what they are looking for.
I was not impressed with that image.
What I was looking for was some large, dark, out of focus area in the image. If there was such an area, and no noise or grain evident when viewed at full size, then I would have been impressed.
What I need excellent high-ISO performance for is in the dark, OOF areas of an image, such as completely blurred out black backgrounds. Make a sensor that can produce such an image grain-free, right out of the camera, and you've really got something impressive.
The image shown was one in which almost everything in the frame was on, or close to, the plane of focus. Even cameras that are sub-par in high-ISO performance can do a decent job with that.
