like I said the min pixel width is 0.25 by default, even without the arnold parameters property.
0.25 means that no hair strand will be thinner than 0.25 pixels in screen space, how much the hair gets scaled up depends on how far away your camera is, and at what resolution you render at. I'm not sure how it's calculated exactly, but obviously the camera distance is taken into account, which must be why you're seeing different results between the camera view and the user view.
