Armor paint is matte by design. That said it is still affected by light, and is not absolutely matte neither.
Take a look at pic related, the paint is evidently matte overall, yet there are colors variations due to the light angle and even some shine on the canon and some parts of the turret.
This is usually replicated with basecoat highlights and a matt finish. It technically isn't correct but they do feel a lot more real that way.
That said there are some tanks around that do look more glossy, may give it a try.
