X100S structurally underexposing and desaturating JPEG's

Because I can't find a discussion of my issue anywhere else on the web, I decided to register an account here in the hope that someone might enlighten me on what is going on.

I've got a refurbished X100S and I really want to love this camera for the combination of it's compact size, fixed 35mm lens and quality. But it's playing hard to get! So hard, that I'm fantasizing about spending way too much money on buying a bulky Canon EOS 6D Mark II with a Sigma 35mm F1.4 DG HSM Art. The reason is, the X100S structurally gives me JPEG's which are underexposed and desaturated. I've addressed this with Fujifilm, but they are clueless and didn't even really investigate the issue, they just started replacing parts of the camera. When the first repair in March 2016 (replacement of "optical unit", whatever that may be, sensor?) didn't change anything in the behavior, they repaired it again in October 2016. They replaced the optical unit again, as well as the "PWB" and "upper hood". Now you know why their cameras are so expensive The sad thing is, it still didn't fix the issue.

To see what I mean, take a look at my Flickr photo stream here https://www.flickr.com/photos/avanloon/ for examples. Take a look at these examples from June 2017 in specifc:
https://www.flickr.com/photos/avanloon/35214607862/ (X100S JPEG)
https://www.flickr.com/photos/avanloon/34994414630/ (D5100 JPEG)
https://www.flickr.com/photos/avanloon/34994428300/ (X100S RAW)
In the first example you see a beach in broad daylight, taken without exposure compensation, which looks as if the sky was overcast. Film simulation is standard. Color, sharpness, highlight tone and shadow tone are all set to zero. EXIF data is included. In this example it's not so much the case, but colors tend to look desaturated too. In the second example a JPEG from the Nikon D5100 for comparison. I think the D5100 exaggerates the color saturation slightly, the sand wasn't so red, but at least the photo is bright enough. The last photo was developed from the RAW file of the first photo. All I did in Darktable was increase exposure by almost 1 EV and saturation slightly as well. I had to do this for all other photos taken on that beach by the X100S as well.

The day I shot those beach photos was the first time I decided to shoot RAW files next to JPEG's. As you can in my Flickr stream, the X100S doesn't deliver terrible JPEG files all the time, but it does happen very often. Take a look at https://www.flickr.com/photos/avanloon/28915124723/ and https://www.flickr.com/photos/avanloon/29247991940/ for another good example (taken between first and second repair of X100S).

As you can imagine, the poor JPEG files took the joy out of photography for me since I started using the X100S. And Fujifilm didn't help at all. Now that I know I can fix this in post-processing I have a workable solution, but RAW files are large and require extra time to process: I'd much prefer it if JPEG's are right from the start.

So my questions are:
* Has anyone else seen this with their X100-series camera?
* Is there a solution?

This question has not been answered yet.
