Well 4 bands I would believe, considering much earlier Russian seekers used two bands in the infrared range to improve IRCCM. So perhaps the PL-8B uses 2 bands in the IR and 2 in the UV.
As to the number of elements, I find it difficult to believe that a 64 element device can be called "imaging". Try taking some image and reducing it to 8 x 8 pixels. That's the quality of image you'll get. I think it would be quite a challenge to get digital filtering algorithm to get any meaningful counter measure suppression at that resolution. So one bright dot becomes two, going in two directions; you have such a small view arc to estimate their speed and you must decide to continue to track one or the other before it is outside the view arc and lost. I guess if your optics can saccade between two targets fast enough, 8x8 would be adequate.
Still, if the target maneuvers so that the flair looks like it is going straight while the target looks like it is shooting off to the side like a flair, that'd be quite a challenge to the imaging paradigm of counter measure suppression. All the seeker gets is a projection of the scene on to its 8x8 image plane. That's really not much to work with.
