An OEM may also source a part from multiple suppliers, of differing quality. As with the "Samsung Panel Lottery". So an OEM sending a model for review, might select one with parts from all the best suppliers, while the one you get off a shelf, is a dice roll. And as you say, a potentially binned roll.
Similarly, with a standard model on a same-day replacement plan, imperfections are likely to come back, with an added site visit cost. But the barrier to returning a customized model is higher. Creating another incentive for binning.
