Correct - these are referred to sometimes at DL as 767-300(g). I've been on them a few times, and once, at CVG I think, we had mid-cabin boarding.
Mid-cabin boarding is one of the real benefits of the 757 and 777 (and the 767-3g's) - if you're in front, you don't have the riff-raff filtering through and smacking you with overstuffed backpacks while you're enjoying a pre-departure cocktail.
