It's not that they are dirty by no means, nor does it have any taste difference. I think that what your referring too, is not actually the skin but the outer membrane that is on the skin. Which is a yellow color, the more corn they eat the more yellow it becomes....
When you scald, the outer skin comes off at a certain temperature... Lower scald temps, will keep the membrane on. Actually a lot of birds in Europe, are hand plucked with out water... so that membrane stays on. They yellow skin color is prized.
