I think the issue is more about the lack of true diversity. Look at music for example - to achieve global success, bands all over the world need to start using western rhytms and melodies, losing the very things that made them unique.

Not that there's no innovation in niches, but those never reach the highlight. A friend of mine is a musician, and was fairly popular in his circles, but has almost a decade ago renounced all pandering to the audience, started playing incredibly complex music, polyrhythms, fractal melodies, uniquely tuned instruments - and has since lost almost all of his audience and the income which came from music. But - and this is important - he's never been both happier and more virtuosic as a musician, it fulfills him like more popular music never did.

Unfortunately, he'll probably never be as appreciated as before and must have other sources of income.

Edit: this is him and a single, weirdly tuned guitar: https://nikopotocnjak.bandcamp.com/
