No, with the exception of JPEG all non-indexed color image formats will be
used as red-green hfields and I am not sure why JPEG is different (I don't
remember making that change deliberately, if I made it at all).  For formats
with color maps POV-Ray will ignore the color value and just take the map
index as height.
