I'm not sure what's going on with HiRISE. Looking at Opportunity and Spirit - the earliest images are the best. But there ARE images AS good as that in each months updates. PHX is an odd-ball because of low light angle, thus having to crank things up to get an image.

Full inline quote of previous post removed - Mod

The first images released of the landing sites were stunning. But subsequent images from HiRISE show a lot of noise and banding.

Without going into the actual image and lighting geometry now, I'd venture a guess that's just a result of poor illumination and really marginal signal to noise ratio. No doubt detectors degrade over time, but this would be radical.
