Your own change to the analogy isn't really all that accurate either: What you are saying would be closer to, saying "This game is cheaper in Android" in the Apple store's product description. I have no idea of what the courts will rule here, but if you are limiting this discussion to whether there's precedent to advertising a store the manufacturer themselves controls, there sure are examples. This might not be all that popular a plan with Cheerios, but perfectly normal with all kinds of items available at retail stores: For instance, Simple Modern water bottles will come with a discount coupon for buying replacement caps at a discount on the manufacturer's online store. Some printers have, inside the box a leaflet for ink discounts. At least one major vacuum cleaners brand will point you to their website for replacement bags, with an online coupon. Or, back in software, if I buy a Nintendo Switch at GameStop, I will still get ads on menus for buying games online, even though my relationship with Nintendo started at GameStop. All kinds of retailers carry the products I mentioned, even though there really is far more profit in habituating the customer to buying the consumables in your own store than in the original item. You could argue whether this is good or bad, legal or illegal, but the examples definitely exist.
