Presumably it's the noticeable 'edge' to the white lettering at the top of the stamp?
Glenn you are right on there.
Michel states that for 802
II the upper frame is brighter
whereas for 802
III the frame is evenly toned.
On the other hand Michel states that 802
II is
braunlila (brown-lilac) and 802
III is
dkl'brownlila (dark brown-lilac)
The former is obviously darker than the latter so something is wrong here.
Actually the Austria Netto Katalog lists
three different colour shades for the photogravure version.
