Here is a photo in my living room of a real shadow from windows. The multiple panes give a nasty "artifact". With artificial lighting these are even more common.
Yeah, I love these sort of images, "reality has a bug". Here's a similar one from Morgan McGuire about halfway down my post: http://www.realtimerendering.com/blog/visual-stuff/
Your reality has Mach banding. A spot of dithering will fix that. :-)

I sometimes see artifacts in the sun-sky, glitches like halos e.g., or an over saturated horizon ...
