It should be noted the panorama shot has a touch doctoring/tomfoolery with it and isn't a 100% true representation of what it looks like on the surface of Mars from the Curiosity cameras.
In what way? I mean, no picture you see is a true representation of what you'd see with your own eyes, how is this modification worse than what came out of the camera?
states is true to some extent - the image of Mount Sharp has been colourised, the image of the Sun inserted from a previous rover, and some regions of the sky extrapolated. However, it's still an exciting taster of what's to come - if you're into that sort of thing.
