This is true.  I can't recall right now why this is the case.  IMEXAMINE needs
some work to be more useful with higher dimensional images.  For now
you would need to use IMCOPY to copy out the plane you want to examine.

This was actually a preconceived feature.  The idea is that one might want
to examine the image display buffer as an image; i.e. you would get
back values from the 8-bit display.  This was considered useful for
situations when some other task, say a data acquisition task, loads
the display, possibly without creating an image or an image in
an IRAF format.
