It's unclear if Apple (who absolutely does NOT want to get stuck with thousands of returns for failed foldable screens!) is being super rigorous in their testing of Samsung product or if they built something to Apple's specs for these tests. I really doubt they are sending over scraps and rejects from the dumpster at the Daegu plant.
They would be able to reject those repairs the same way they have done with all their blunders. People just folded their devices in the wrong way which made them break.
