For float/double images there is the setting in the preferences. So this
is not a bug.

Title:
  Wrong gamma of 32-bit float images in Control Points editor

Status in Hugin:
  Won't Fix

Bug description:
  Hello

  32-bit floating-point images (from RawTherapee) are overexposed in the
  Control Points editor. Maybe they have the wrong gamma applied, or the
  embedded ICC profile is not used?

  If you open the source images in GIMP-2.10.4 you will see them
  correctly with the correct gamma. They are of course very dark, so
  maybe the CP Editor is trying to make them easier to view for the user
  through dynamic range compression and increasing exposure. If that's
  the case, then nice, but the large CP editor magnification box, the
  one that magnifies the few pixels you are hovering over when placing
  new CPs, still shows a completely black preview, as you can see in
  screenshot screenshot_20180806_081643.png.
