When I hear "Posterization" I think iResolution with Sharpen>-2

Really? I have never seen that type of artifact with ires and have looked at over 1k images. Making contrast and color adjustments in PP on jpgs maybe a few times it has popped up.

Perhaps I'm giving it the wrong name.

What do you see when you use  Ires=on and Sharpen=0 ?

Oh I think I know what you mean! I see excessive sharpness and more halos. The edge enhancement can give the image a hard over sharpened look that sort of looks like contrast enhancement. The image looks flat and fake. Looks digital! Like what happens when you turn up your TV's sharpness too high.

I think of posturization as a color artifact. Color breaks up and distorts. Color ramp is in a stair step like pattern instead of a smooth ramp.

Ires can also smudge fine detail in some parts of the image even when set to -2.
