exr exposure

Hi,

we are working on a project that involves some skyboxes and reflection maps that we've been provided content for, in open exr format.

When I import the exr format in Unity, it just works. But I have no control over the exposure I want to use, some look fairly grayed out, others look just too dark.

It there a control over this ? Or is exr format just meant to be used for light maps ?

Thanks
