So perhaps Epicurean spirituality is the recognition of the profound, intricate, beautiful, blissful, subtle, elating, humbling and tranquil nature of the gods, and the practice of attuning our own nature to that god-like state.
I think in response here that I would say that probably either as a part of anticipations, of pleasure-recognition, or of both, that there is a disposition to recognize the profound, intricate, beautiful, blissful, subtle, elating, humbling and tranquil nature of anything which we would expect to find the highest manifestation thereof in the highest level of beings which we would expect to exist within the universe.
So those characteristics you list are all things that exist in varying degrees in the things we come into contact with here on earth and would experience as part of those interactions, so we have a faculty of recognizing those characteristics which does process data received through the eyes/ears/tongue/nose/skin, but that faculty of recognition is probably not itself a part of the eyes/ears/tongue/nose/skin.
So the question that is probably on the table is how this faculty of recognition operates, and whether it can receive stimulus that is not strictly part of the eyes/ears/tongue/nose/skin.
1. Is this faculty purely operating in accord with the "etching" that it has at birth?
2. Is this faculty operating purely in accord with its etching plus its influences by the things we see/hear/taste/touch/smell during our lifetime after birth?
3. Is this faculty operating in accord with its etching, plus what we see/hear/taste/touch/smell during our lifetime after birth, plus something else that is perceivable by the brain through mechanisms not currently understood by science, but understandable by science after additional study through techniques not yet invented? (For a gross example, attempts to study claims of "ESP" or "gravity waves" or "cosmic rays" or similar claims of repeatable phenomena, all of which - if proved to exist through repeated observation - we will presume due to our prior conclusions to be the work of a "natural" and not the work of a "universe-creating-supernatural-being" phenomena? I suppose even "contact with a UFO" or "contact with an alien race" would fit in this category if they actually landed in Central Park and said "We are here to serve men" and gave us what we thought at first was a table of profound natural laws but which turned out to be a cookbook. )
