Aerial imagery in mosaic dataset has speckled look

I've loaded aerial photography into a newly created mosaic dataset. The resulting raster, when viewed in ArcMap, has an unclear, speckled look. I've tried several options, including defining overviews with both bilinear and cubic resampling. I've also tried starting with images having pyramids already defined. The result is always the same. Is this normal? Any ideas on how to improve? Is this something that is even controllable when creating mosaic dataset overviews?

Attached the imagery as is and a mosaiced ECW version that is closer to the desired look.

thanks.
