Using sophisticated signal processing (which has been standard for ages at this point) gets you some gains, sure; but it's not magic and high field systems have better resolution. Worth noting: A lot of the focus on advanced signal processing has been focused on scan speed, and main field strength and homogeneity is only one factor in resolution. You need high quality gradients too, the finer the resolution the more precise everything has to be set up or you are just smearing the signal around in space.
