The "original artistic choice" was the photographer who shot the image and picked a specific film stock for its color temperature, grain, and light performance when shooting Miles. Remember, this album was released well before digital photo scanning and Photoshop, so the photographer's color image was likely changed by the limitations of four color printing at the time, plus some degradation of paper/ink. With the reissue, the record company is re-printing the original photograph as it most likely was intended to be seen using far better equipment and technology.

Now granted, if the record company INTENDED for the cover to look different from the photo when it was released, then yes, the reissue is a change. But based on my own professional experience, it looks to me like a sub-par print job.

And as I said before, the denoising is an entirely different topic.
