Hardly fictional, it's a pretty accurate representation of what Jupiter actually looks like. The main reason for using this technique is because our turbulent atmosphere blurs any image. Taking a video allows only a small percentage of the clearest frames to be combined. A spacecraft doesn't have this problem. The technique is called lucky imaging: https://en.wikipedia.org/wiki/Lucky_imaging https://en.wikipedia.org/wiki/Lucky_imaging
Stacking improves signal-to-noise ratio but does not introduce details that aren't present. A stacked image can be more accurate than a single frame as camera artifacts are reduced.
