I have seen the same thing in my HDR images taken with Olympus OM-D 1MkII,
but I have attributed that to the fact that I have been taking images of a
single/few high luminance spots (lamps) in a dark environment and I have
assumed that there actually isn't that much color.

I have been using both darktable's HDR functionality and a program called
HDR Merge. Both produce a linear 32 bit DNG file that I then process
normally with exposure compensation, filmic v4, local contrast and color
balance. At least in some of my images HDR Merge produced more saturated
images but in some cases there was strange noise around the moon and I got
a better result with darktable.

To my knowledge if you use darktable's HDR functionality it is just
"stacking" the images together without any preprocessing.
