It is the question of white point and black point, on input and on output of
the brightness/contrast/gamma correction. Where to cut off input, and then
where to pad lost data on output.

I even suspect original tiff/EXR may come from Natron/Blender/something (CG tools) that was using scene-referred workflow .....

so while in some sense using this  image might be wrong , ability to get useful info out of it might be useful anyway.
