I can't hear much difference in the Studio voice:

I'm fairly sure I couldn't tell Studio voices and real people apart in a blind test.

It would be a good test. I don't think they are yet indistinguishable, for what it's worth.

I don’t think they’ll ever get undistinguishable because humans have variability. Too much consistency and it starts having an artificial smell. Look at ChatGPT for example, you could read a perfectly writen answer and yet kind of sense it was written by ChatGPT..
