If so the problem would have showed up in tele shots as well. The effect decreased towards longer focal lengths.

We are not privy to the shots taken. So, we can only take guesses. But usually, wider angle shots are taken with longer exposure times than tele stuff. We already know from the K7 that the SR system gives a blur problem at certain low-ish shutter speeds due to mirror slap moving the sensor.
So if that a difference between the taken wider angle shots and the tele shots, that will explain it partly.
Also, it could be that the longer lenses are more heavy, or the camera is held differently, which might absorb more energy from the mirror slap, making the SR assembly move less with the tele shots.
