image rendering

I know the CSS property: image rendering is not widely adapted by most browser including up to present versions. Pixelated and crisp-edges are the only two values which are compatible with current browser, IE you must use a vendor prefix and another property. My question is; is there a noticeable difference between the browsers default smooth interpolation and pixelated specifically ? I have image-rendering set to pixelated for an image, maybe there is a slight increase in quality, over the default or auto !
