Especially when looking at the middle sequence, the sunny day, I think there is something wrong with the camera.Often the white balance is wrong. Both exposure and white balance changes very suddenly from one picture to the next, both for the good and the bad. It is not even like the settings are locked for some time - they just changes.
Mapillary is a good example. One images is pretty good (perhaps slightly over exposed) but the next looks like you have put on sun glasses. There is nothing to justify this sudden change and the dark images are wrong.
I have a Garmin Virb and it produces much better images than this one.
The issues might be solved by a firmware update.
If you are not in contact with Garmin, I think you should get it.
