Does the world loose contrast and saturation in your eyes when you step outside :- ) ?
Sometimes, according to my iphone photo and even my dslr, yes :)
But maybe the above comparison wasn't a very fair one. Equally unfair would be me posting here some photos trying to prove that yes, the world outside is desaturated. Because the truth is you can take photos to appear sometimes quite green and saturated and sometimes desaturated. It depends so much by a lot of things, like what lighting is, is the sun in front ? back ? are the trees wet ? dusty ? the white balance and so on.
But sometimes the movies, or even casual photos (with auto settings and no color correction) can be less saturated than many renders. But that has more to do with the user setup of materials.
