Is this agency you refer to a marketing or design agency? If so, this data point is most likely somewhat deceptive. The core competency of a marketing or design agency is creative work, and naturally you want exceptional talent in that respect. Such an agency is generally going to be building straightforward websites that don't require particularly skillful software engineering. (And even if they did, it'd be an option to contract out, whereas contracting creativity out is not - as far as I know - a real option.) If you look at the salary of an equivalent "Head of Development" and "Head of User Experience/Design" at e.g. Microsoft I suspect you'll see the opposite salary situation because of the relative focus of the organisation (although Microsoft is putting a lot of emphasis on design these days so who knows?).
