That's really interesting. I haven't ever owned a bottle of DN (samples only), and yet I can somehow see where what you report might occur. Am familiar with the other two, but perhaps haven't had them long enough (actually I swapped the Etro away) to run into it.
I will note that there is a tendency to rubberiness in all three of them, and yet not in the Rahat. Perhaps my rubber is your burning leaves.
The only scent that has ever changed on me is Ce Soir ou Jamais. This got extremely and potently wine-like, which is a facet of the fragrance in its pristine condition, so maybe it is some intensification of certain notes that is to blame.
