The DIRECTV image above is soft and lacking details, but there's no edge enhancement (including no artificial sharpening of edges that are supposed to be somewhat soft like the tree branch in the upper-left corner), no distracting distortion, no color damage, and no chroma shifting that I can see. Far less mosquito noise as well. With its many problems, the Dish WA image may still look more detailed in some areas by comparison, but most (not all) of this
comes from the edge enhancement brightening/darkening and/or merging details and/or
artificially sharpening edges so that some things stick out more than they normally would.
