Using exr ?  There is a bug where the HDRI has values which exceed a 
half float(a). IIRC. Values end up as HUGE_VAL and you get artifacts 
that basically won't go away with normal -ish tweaking.

(a) - POV_Ray's current exr support only works with half float (16 bit) 
exr files and many .exr files found today on the internet use the full 
32 bit float format and those, sometimes, have values > 16 bits float max.
