I'll be the old Francksoy nuisance again :bigsmile: and tell that there is no way to answer this question by looking at an original scan. A scan is not a crystal ball. There is absolutely zero evidence that there would be any kind of correlation between an original PIE/PIF scan and a disc's lifespan, actually in my experience and with my own data, I think there is enough evidence that this correlation doesn't exist at all and is a pure figment of the imagination.
Only thing you can do if you doubt, is to re-scan after some time to see if errors significantly increase.
MCC004 is supposed to be a very stable MID so no reasons to be too worried.
But... for archiving, the way to go is to burn at least two discs of different makes. You never know what can go wrong. It's a far sounder approach than burning 1 disc only, and decide if it's good enough for archiving by looking at the scan. Play safe.
