Yes, however just because a gene is Dominant does not mean all four genes present in the plant for that character are "purple" genes.  Only one Dominant purple gene of the four that can exist is needed to be purple colored flowers. For a Recessive to "show" completely a plant needs all 4 recessive genes (in tetraploids) to be present.  You only need one Dominant in each parent for each parent to be purple.  There are recessives that go along with the Dominants that can emerge when two recessives from one plant meet the same two recessives from another plant.

So when you cross two purple selfs you might get some roses, some plicatas, some whites and glaciatas if the genes for those are there not expressing in the two purple flowers.  Depending on the type of purple the colored flower you are using you may also get carotenoid amoenas as well.  

Now a rhetorically supposition... Is purple form anthocyanin only or a combination with carotenoids as well?  An anthocyanin purple self flower could have all four genes for carotenoid amoenas and not show it because it produces no carotenoid in the petals.

Also just to be sure you understand this comment is correct....
"You have both a dominant pattern--(self) and a dominant color--(purple.)"

However, the two genes are independent of each other.  So you could get the purple form one parent and also get all plicatas from each parent (i.e. no self gene) and end up with a purple plicata.
