Preview is... preview, no more. Press F4 and you will see JPEG preview embedded
in NEF. Yes Nikon Embedded JPEG preview (more than one depending of NEF
version, but not the full image size i think)

All RAW files format use this technic to be able to display RAW on TV or on
camera screen without to demosaicing image data !

Raw import tool do not use this technic. It run on real RAW image data, not on
JPEG embedded image to display preview in this tool. In fact, Raw import will
always display Raw demosaicing result (worked to a 1/4 size of Raw image size -
feature from libraw)

Note : Exiv2 is not used there, but libraw...
