The default constrast stretch in OpenEV is suboptimal but that is easily corrected by manually selecting a stretch range. There is no evidence I can see that libtiff has problems with this image. But I would not be surprised that many applications do different things to convert this to a displayed image. The TIFF file itself does not force a particular display approach.
