Yes, nice classic Mars image. If you compare it to the current planet, there are changes and the albedo patterns. Syrtis Majoris does look somewhat different, with an extension to the left that is not visible now.

I think that Jupiter or Saturn would benefit more from that reprocessing effort, because the atmospheric features are less contrasted and have different colors. One long standing question (for me) is if the general color of Jupiter has changed or not over the decades, independently of the cameras and filters used.
The GRS looks less saturated today than in the past, although the bands still look very much the same... But it might as well be the other way around (the bands might be getting more contrasted).

It's easy to dismiss any differences based on poor hardware and filter combinations (like Voyager's OGV vidicon compared to Cassini RGB CCD images... ). Perhaps satellite transits can be used to color balance the old images.

The GRS has become fainter and is about a quarter of its size in the late 1800s. It may have been even larger than that at one time, but that is speculation, since before the photo I posted we are dependent on drawings.
