When I open the files in QGIS or ArcMap, they assume RGB for the
default visualization but I don't know why. One of the files looks
great in ArcMap by default (but slightly too white, I believe),
while it looks very much too white by default in QGIS, although the
QGIS display can be fixed by color re-configuration. For the other
file, it is QGIS that displays a sensible image by default, whereas
ArcMap displays it with very exaggerated contrast (the default QGIS
display is brownish-rusty like Mars while the default ArcMap display
is brightly reddish-white like Jupiter). So the score is 1 - 1 for
the ArcMap/QGIS contest... I think the very different default
displays confirm that the files are troublesome or corrupt.
Sounds like different default gamma correction values.
There are a couple of different default gamma values,
so unless the files specify their gamma, the two applications
could easily pick the right default for different pictures ...
