Yes, a change in the pressure angle may not be visible with a naked eye, but would be visible in contact pattern. If the pattern flank to flank shows misalignment tip-root then it's a pressure angle problem and you need to check the blade geometry after sharpening.
If one of the cutters in higher than the other, e.g. because its axial position has been set like this, or due to some sharpening errors its resulting cutting edge has been moved away, or the vertical work spindle is off, or the cradle is worn out and went down, then you should see a toe-heel misalignment.
I assume this is not caused by the cutter runout. It would be pretty obvious as you could hear it while the machine is cutting.
Hope it helps,
