However, the question was if there is a way to detect the colour space of

I think that it is wrong to consider EXR's color space to be "well defined"
even if the data is not supposed to be gamma (or log) encoded. There are
many contributing factors to color space beyond mere gamma encoding such as
the primary colors, and the relative strengths of those primary colors.
