You should be good with the run out you have now. Keep a watch on it and the bolt torque after a few miles. The difference in rubber composition isn't uncommon. That's just Chinese QC.
And yes, I've seen a sprocket that the center hole was nearly 1/4" out of center. Now that one would have caused some problems. Sad thing is there are guys who would not see it and try to run it on their bike then come here and ask why their chain keeps coming off. And that's a fact.
