If you’re using a camera as a scientific instrument, normally you try to make the picture as real as possible. Conjuring up imaginary detail just isn’t acceptable.
However, you can use false color to highlight whatever it is you’re interested in, and this is a common practice in areas such as electronics microscopy, thermal imaging and astronomy. Even that might not be acceptable is you happen to be interested in the color of different things.
In normal everyday photography, the user usually isn’t interested in authentic textures or colors. Fake internet points are far more valuable to most users, and Samsung knows this.
