God's acceptance of Noah was unmerited?

The theory I heard was that while the rest of the Sethites had intermarried with the Nephilim and Cain's line of descent that Noah's line of descent was pure Sethite. Is this a Jewish understanding?

Some Jews have advanced this view, but it is not a universally held belief.
