That guess is absolutely spot-on. If (e.g. for the sake of upsampling 
with interpolation) you choose to go via a pigment function based on an 
image_map, rather than using the image directly in the height field, 
then by default the parser will treat the image like in any other 
image_map: It'll presume that the data is actual colour data, and apply 
gamma adjustment to it.
