Image Extension for Server 10.1 not rendering image correctly at cache scales

I have an NTF raster mosaic served via image extension for server. If I do not use tiles from a cache it looks as it should. However, if I create a cache then the color of the images goes wrong in certain areas of the image and at certain scales, ie when zoomed into an area where clouds are present or other significant variation in pixel value occurs. A sample of these bad results from the javascript api is in this picture:

This problem occurs when viewed in Flex viewer, ArcMap, and ArcCatalog preview window as well, and occurs no matter how many scales I build the cache at (I tried 3, 4, 8, 15, and 20 scale levels, maybe a couple others). Is there a way to improve cache generation so areas of significant pixel value variation do not cause this problem?
