From looking at your last picture
It's possible that her left (right side as we view her) eye hole might be a slightly different shape/size than the other. Whether they truly are different or not is hard to tell from the pictures. Lighting, shadowing in the clear parts of the eye, and eye position can all affect how we perceive the overall eye shape.
It does appear in your last picture that her left eye might be positioned slightly lower than her right (the dark circle surrounding her right iris is completely visible at the bottom but isn't on the left side).
Even if the head has built in eye pockets eyes in vinyl heads can move around a bit from the squeezing of the head during installation on the body, wig and head cap removal, etc. So don't spare the eye putty. Due to the softness of the head you might want to use a bit more eye putty than you would on a solid resin head.
