> Apple doesn’t see factories purely as stores

At Apple's scale, you basically can't operate like this. Placing an order for 50 million iPhone screens is not a consumer-grade request, you have to customize and coordinate your orders to get all 50 million delivered. It's hard to see the genius in this, the advantages you've listed are all courtesy of scale and liquidity.

Huh, courtesy of scale is because of 50 million customers were convinced that iPhone has quality enough to pay premium over 100s of other phone models. No one is stopping Dell, Acer, Asus, Samsung etc of the world to put order of 50 million widgets and get best quality at cut throat price.
