Sure.  Look at this gist:  https://gist.github.com/4679014

It includes the same image file, in EXR, PNG, and JPEG formats.

The EXR file is the "master", and of course is encoded in linear-light, so shouldn't have gamma issues (haha!).  The other files have a gamma-correction of 1 / 2.2.  In the PNG, there's an explicit gAMA chunk describing this; in the JPEG file it's implicit (because of sRGB).

The PNG and jpeg files display identically with every program I've tried -- eog (gnome), "display" (imagemagick), web browsers (firefox, chrome), "geeqie" (not so common, but a nice and generally capable image display program).  Most of these can't handle EXR, but "display" does, and it displays darker than the 8-bit files, similar to the way iv does.

"iv" displays the PNG file identically to the other programs, but displays the EXR and JPEG files much darker, suggesting that indeed maybe the issue is that iv is doing the wrong thing on _display_: using the correct gamma adjustment when reading jpeg files, getting
