From the movie "No Time to Die":
Nomi: The world's moved on since you retired, Commander Bond. Perhaps you didn't notice?
Bond: No, can't say I had."
Why did Bond use "had" and not "did"?

Note that the responder doesn't say the participle (had noticed) required with a perfect auxiliary have. The questioner uses the auxiliary for an infinitive (didn't notice), not a participle. Consequently, if you filled in all the missing words, it isn't ungrammatical, just not parallel: Perhaps you didn't notice [it]. I can't say I have noticed it. This violates the attempt at reduction, but is clear enough. And this is a movie, not real speech.
One of the main reasons to use past perfect is another action in the simple past that precedes it:
"Perhaps you didn't notice?" [simple past]
Bond: No, can't say I had. [had noticed]. I can't say I had noticed before you mentioned it (implied).
Other examples:
I had noticed that she cleaned up the room.
I had seen the movie before he mentioned it.
