Images are "shopped" before they even emerge from the camera these days.
Well - since the Raw data from a sensor need to be remapped and massaged to display an image anyway, the answer is "well, duh". EVERY jpeg is affected by settings regarding curves, white balance, exposure, sharpening, contrast etc.
If you wanted a "pure" view, you would have to publish the Raw file from the camera and let each viewer change the curves, white balance and what not to their own taste, adjusted to their current ambient lighting and what they thought the picture should look like.
