Depending on the system you buy (and, you get a price break when you buy those specific systems), you can only acquire software digitally, through their stores. And, it’s all in how you define the market. The market in my example is “digital downloads through the Sony Playstation Store to Sony Playstation brand game consoles”. The market in your example is “digital downloads through the Apple App Store to Apple iOS/iPadOS devices”.
If you redefine your market without using Apple’s trademarked product names, then I’ll redefine my market without using Sony’s trademarked product names
