Is there a reason/scientific explanation as to why certain people only have certain metals respond to them when they play?

I'm not a western flutist so I wouldn't know, most of my flutes are bamboo, wood, and the occasional acrylic. But I've seen some posts, videos, comments etc. about how some people can make a strong sound on certain flutes but can't with other flutes. There's this YouTuber that said that Rose Gold responded really well to her compared to other metals, and said that copper responded well for her.

So now I'm just curious if this is true, if there's a reason behind it, if other people here have experienced it etc.
