Rlsny- First of all, kudos to you on the certification, and for the incredible find! The impression on your 130 is immaculate.
Hopefully, I would also like to give insight to your topic question by sharing from my own experience regarding the differences we might see in re-issues. For me personally, the paper has been the most qualifying factor that sets them apart from their 1869 counterparts. It might not be the same for other sets of eyes, but I always look at the paper first.
Here is a 127 reperfed at left and pulled perf at bottom right I found a while back that has since been certified.

I was sifting through a collection of pictorials and chose this one the moment I saw it. I did not consider the blue cancel, which is uncommon on re-issues, and I did not examine the design or even the back of it for hints of a grill. The paper itself was a dead giveaway.
I think it's helpful to include this in your thread, otherwise people with no experience in handling them may think that the design must have exceptional clarity in order for it to be certifiable. But that has not been my experience, and certainly is not the case for the ones I've seen.
Actually, I did not think the design could look as nice as the one you found. It has changed what I thought I knew about re-issues and I appreciate you posting about it!
