We could always add to that thread a brief and simple "User's Guide to LV" to help problem-solve before neurotic bag owners post. For example:
"Normal" = slightly different stitching (spacing, double-stitch, etc.), different coloured hardware (seriously, no one is looking at your zipper and thinking "woah, that person's zipper doesn't match the D-ring"), not perfectly aligned canvas patterns, a wrinkle on your Speedy's handle(s), anything that is "crooked" (pull out a protractor or leveller; if it's more than a 5 degree angle then it's crooked and needs to go back to LV), etc.
"Not Normal" = premature canvas and/or leather wear (i.e. cracking, peeling, bubbling, etc. within 1-2 years given that the rest of the bag is in reasonable condition), hardware falling off, the item is flashing gang signs, etc.
I'm going to throw out a potentially unpopular opinion (so gird your loins or just keep scrolling) but, if some people are THAT concerned about the asinine details that they otherwise wouldn't bat an eyelash towards affordable and/or contemporary brands, then maybe LV is just not a good financial and/or lifestyle fit for them.
