Fujifilm xt-10 raw files underexposed in darktable at high iso
In some conditions raw files taken with an xt-10 fujifilm (firmware 1.30) are underexposed.
Camera settings are f2.8, shutter on "auto", ev comp set to 0. This should produce 4 images with the same "brightness" level. Iso's tested were 1600, 3200, 5000, 6400. Above 6400 the fujifilm does some other processing that may interfere.
I have confirmed with all modules disabled this issue persists.
Darktable version 2.4.1 (from flatpak).

Finally, it may be worth noting the following https://adambonn.com/my-love-affair-with-the-fujifilm-x-pro1/xp1-seventeen/
The camera is "iso-less" above ISO 1600, so it may be writing the raws equivalent to ISO1600 even though it's at ISO6400, expecting darktable to detect this and post process it. Perhaps this is flagged in the raw file? I'm not sure, but this could be part of the issue.
