When selecting a camera, how would one go about testing it for unacceptable

important spots. Would they show up as white dots in an otherwise black shot? Or the reverse? Or something else? Is there any point in trying?

Here's some of the ones from Dave's *istD (I count six in this section):

That's unchanged from the original file, just cropped to highlight the worst section, and at 100%, ISO 1600.
