The page I use has a setting that allows you to adjust strength. this was at 0.55 strength I think. At lower setting you get a picture closer to the original but obviously less refinement. At higher settings you get higher "quality" but more deviation from the input image.
For comparison, here's the same sprite processed with the same query but at 0.85 strength. Seed is obviously different as I can't change that but as you can see there's a pretty radical change from the input image.
