With Cornerfix I just made one profile for infinity and around f/8, so that at wider apertures the profile wouldn't wipe out too much of the natural vignetting. From my understanding, the color shift issue is more dependent on focus distance than aperture. At infinity, the rear lens element is the closest to the sensor and therefore the angle of incidence of light rays to the pixels along the edge will be the most oblique.
i only correct the color shift with the lightroom plugin as i prefer to keep the vignetting. i thought the same was possible with cornerfix? focus distance is the biggest component, but aperture plays a role too as it also effects the angle of rays hitting the sensor.
