Either could be. You adjust the gains so that you see equal knock levels reported on all cylinders. Typically the cylinders that are further away from the sensor need higher gain so I would say if the knock sensor is somewhere near the centre of the engine on these then the bottom set of gains look more like what I would expect.
The best frequency for knock detection can be biased by many modifications so what works well for someone else may not be right for you. For instance hanging a different turbo/manifold off the side of an engine will usually change its knock signature.
