Not only do different grexes had different characteristics but individual plants within the grex can be quite difrferent as well. The stance of the dorsal sepal is of course strongly influenced by genetics but also, as you've suspected, the age of the flower and by culture as well. For example if you are growing your plant near (but not in) a window so that the light it receives is highly directional, the flower will "point towards" the light and the dorsal will not stand as erect as if it were in the window and "looking up" towards the light.
Do you know what your cross is?
