No. What I mean by enamel is the sheen. Walls and ceilings are usually flat or low sheen.
Trim, baths, kitchens, utilitarian areas are usually enamel.

If you are painting a bedroom, hall, living area you would probably use a flat or semi flat finish. Those paints are usually self sealing if it is a good product.

If you are painting a laundry, kitchen or bath you would want a higher sheen (enamel). Those products are easier with a primer/sealer first.

Whatever product you use, try to get the one with the most acrylic in it.
There are different grades of water base (latex) paint.
There is latex, which like it sounds is rubber. It is no good.
There is vinyl, which is slightly better.
Then there is acrylic, which is the best.

There are also blends of all these. Vinyl/acrylic, Acrylic/latex etc. What you want is 100% acrylic for enamel.
For flat try to get as much acrylic as possible.

I am not familiar with Benjamin Moore products but i just looked at their web site.
As you can see, the products list their resin base. The Aura and the Regal, look good.
They have a 100% acrylic resin base. That is what you want.
The product called Ben lists its base as acrylic/latex.
that is what you don't want.

It all applies the same, so you may as well get the best product you can. It will look better,longer and most times the better product has better coverage.
