I believe that the intention behind it is the most important thing. If you truly care about learning and growing, and you do it with an open mind and heart, respectfully, then go ahead.
I don’t know much about cultural appropriation but I’m sure “cultural exploitation” happens: When the intent is selfish, for showing off, or to make a quick profit. That’s when the line is crossed.
Having said that, it’s best to ask an experienced person from that culture. But, even then, they probably don’t speak for everyone in that culture…
