Color matching is tough because a given camera might over- or under-sell certain hues. Purple is a tough one in particular, since RGB sensors and displays have trouble accurately representing purple specifically, and things like camera firmware and display firmware must do compensation in those hue ranges in order to display it at all [

To give you more data, here are some additional photos and videos which show Audis in Merlin Purple. The color seems more muted in these images than the Chinese car's version of purple. But... hard to tell for sure due to the aforementioned stuff.

Make sure that you see a sample of the actual dried paint, before committing to the final spray.
Footnote: Some cars these days are getting
chromaflair colors (I've also heard them called "
hypershift") which cause different shades to appear and disappear as the lighting and viewing angle changes. One of the comments in one of those links above make it sound like the Merlin Purple is in that category, looking almost black in certain situations. Which I personally think is awesome, but I'm not sure if that's what you two are looking for.
