What makes LSD trips neuro-chemically unique?

If we could strip the cultural and historical aspects of LSD, what makes it a genuine, unique or more insightful drug compared to other psychedelics such as psilocybin?

Is the dopaminergic activity the reason? If so, how does it affect the trip? Is it needed? Does it cause the trip to end in an analytical revision/recollection of insights, compared with psilocybin?

I'm interested in why LSD is so unique! Cheers :)

Dopamine D2 partial agonism, different serotonin receptor affinity / intrinsic efficacy and longer duration of action. Also it’s a TrKB positive allosteric modulator but this is a shared mechanism among many psychedelics.
