I can spot a very marginal difference in there.
Without know anything about the exact conditions here, I'd say that this is perfectly normal.
VC/IS/VR/OS/... introduces a minimal degree of jittering. After all you have a "loose" elements that is moved according to the shake. The IS counteraction is performed according to a certain frequency. At the end of the day this means "steps" and whatever motor is used to control the motion it is never perfect.
That being said I have doubts whether this aspect is really relevant in the real life.
The more significant impact from an optical image stabilizer is the introduction of a potentially higher degree of decentering and a reduced long term consistency.
