in my opinion, you have to lower the exposure in Softimage to look at the image and see it properly, but we really don't have any HDR tone mapping toolsto deal with the highlights. It's tone-mapped in Photoshop. It's an HDR image, so it can have large yellow or red values and when you just clamp that down (i.e. truncate value above 1.0) to 8-bit like the fxview does it looks weird. You can click down in the fxviewer to see the pixel color values.
Photoshop is probably showing you what you really "want" to see, which is an 8-bit snap shot at a particular exposure, with something to smootly filter out the highlights. How well does the image work in base lighting? I think it probably works fine. try launching imf_disp at the softimage command prompt. The recent versions of mental ray's imf_disp tool have tone mapping and exposure controls in the view menu.
