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.
