Upon further experimenting, most exr files do show up in digiKam, 
completely with displayed thumbnail - I'm not sure why the first exr 
file didn't show up.

Also 32-bit floating point tiffs that are saved with thumbnails also do 
show up in digiKam complete with thumbnails. I've been saving tiffs 
without thumbnails. Sigh.
