"So I'm assuming that what you were getting at is that no matter what kind of subjective experience we're having, it is unique to each individual experiencer. Do I have that right?"
Ambiguity remains...I can always claim my experience is unique to me, that is trivially true. But I don't think I can claim that it is unique in a way that others don't/can't understand my unique experiences - there is too broad a base of empathy (for even the most odd experiences). So in what way is your subjective experience unique?
What differentiates YOU that asks WAIMANSE? from ME that asks WAIMANSE? If I were not me, I simply would not be, there is nothing contingent ... that doesn't necessitate that "I" be of a unique kind.
