Yes, almost everything you see has been "photoshopped" (retouched or at the least color corrected).
You're looking through a non-color-calibrated monitor that, if it's a laptop, tends to have inaccurate color representation even when calibrated by spectometer. Colors on a monitor will never have accurate color representation compared to the actual physical object because there are too many variables: Image color, color correction, monitor color, your personal color perception including any deficiencies, in addition to green having the widest spectrum of color perceivable by the human eye. Then, considering most images have some level of retouching and color correction after
they're photographed, you have to x2 everything based on the person applying that color correction.
Just for fun, take this color test to see how well you see color.
TL;DR - Things are never, nor will they ever be, as they seem.
