No, this is not a case of developed Se. The fact that I find these instances rare and they do not pre-occupy my conscious mind and that Se does not rule my sense of perception as a whole suggests inferiority. I would argue that the word "development" is even often misused in these instances because by "developed" what we really refer to is differentiated, but if my dominant perception is ruled by Ni, I cannot and will never differentiate Se into my ego as an ego conscious perspective since it is the very perspective that I reject.
Any type with Se as a part of their function stacking can do the above but what separates them from ego-conscious to inferior Se types is how and why they do it. You won't see ego Se types run around yelling over how awesome the thunderstorm is. While the thunderstorm itself might be a powerful experience that they enjoy, when one is naturally attuned to this kind of sense data you are also capable of separating what kind of Se content is valuable or reasonable over other kinds of Se content.
Just like how inferior Ni can appear as paranoia and reading intent that's not there and the dominant Ni type would automatically dismiss the inferior Ni type for this reason since I know when they are reading too much into things, a dominant Se type can tell an inferior Se type similarly when they are getting over-excited and reading too much into sense stimuli. There is a level of normalization when it comes to your dominant perspective.
