Though artist acrylics can vary in consistency, quality, glossiness, durability etc. But that can miniature paint too.
I seriously doubt
GW or Vallejo etc have some secrets formula to make their paint so much better then any other.
And people use artist acrylic to paint just as small detail on the canvas as a miniature figure.
It's not a matter of 'secret formulas' as simply that paints are formulated differently depending on their intended purpose. Model paint, craft paint, artist's paint and house paint can all be Acrylic, and as such would all technically be usable on the same things... but you'll get fairly different results from each.
Model paints have a finer pigment, different viscosity, often a shorter drying time, and tend to adhere better to miniatures than most other types of acrylic paint.
