I cant speak for new york , but i can speak for new jersey .It sometimes depends on where exactly in NJ they are from .For instance , in places like Perth Amboy ,Newark ,and Trenton ,Camden ,thier Dominican populations tend to be lighter becuase most of them come from special areas in dr .(Newark,San Jose de Las Matas-Perth Amboy La Vega and Santiago-Trenton and camden also have many Cibaenos )they are all from one place ,but when it comes to places with very large Dominican populations like Paterson,Passiac, Jersey City,Union City , West New York ,North Bergen,Guttenburg,some parts of bergan county ) there is alot of diversity (as in regions in DR people are from) ,but i will note that in the hudson county area there is a large number of Black surenos (as in they are physically black and happen to be from the southern part of the island) many also move to predominantly black neighborhoods like east orange , irvington, black parts of Newark ,Hackensack,Teaneck,Hoboken(projects) . Most are Capitalenos ,but i have also met alot of Sancri's ,Boca chicas,one san pedro,a few Banilejos(most are light skinned or white) ,other than that not too many people form anywhere else .Then you have many Haitians claiming to be part Dominican ,just to fit in with the Hispanic crowd(I've seen it sooo many times ) ,alot blacks do the same as well .so, sometimes the person can be lying.
