Hey didn't realize I was answering to a contributor! So, I started creating an issue in the repo, and as I was creating a side-by-side-by-side comparison of A=orig, B=guetzli, C=jpegli ... I realize that wait-a-minute, Jpegli is actually doing a better job at preserving the original image :D The B/guetzli version is actually too smoothed, obviating a couple gradient anomalies observable in A/orig. Conversely, C/jpegli actually better "preserves" these imperfections, by not smoothening the broader area into a gradient that is "smoother" but loses some detail. So, not creating an issue :D. If you wish to see the image and do the A/B/C comparison yourself, it is screenshot 14 of videogame [1], direct link [2]. The area where I noticed differences in gradients is the top / top-right area with black arches and blue fog. Thanks for Jpegli and Guetzli.
