I get the direction you're trying to go in, but I think this metaphor is flawed. If all I've seen in life are mediocre street musicians, and then one day I go to some concert and it's the best thing ever, sure that's going to change how I see the street musicians from before.
Replace with food and its even clearer. Going to some top of the line Micheline star restaurant _will_ alter how you look at food for the rest of your life.
Watching a movie in blue-ray full quality no compression _will_ alter how you appreciate streamed movies for the rest of your life.
You can still appreciate it for what it is, but it will forever have that relative smallness.
I mentioned Micheline just as a commonly recognized ranking for restaurant quality, but its irrelevant to the point. Based on whatever internal ranking of food that you have, if you suddenly experience something that goes off your internal chart, you will have to re-scale your ranking to make it fit. I.e your previously ranked experiences will be affected.
Maybe as a whole its a poor example though because enjoyment of food is a multi-dimensional problem. Whereas obliterating a dopamine receptor is one dimensional.
