Apple's hypocrisy is a longstanding issue with regard to their apps vs 3rd party apps. As I recall when the Green Bubbles first happened in messages someone pointed out that Apples own design guidelines specified a minimum contrast in colors or they would reject apps, and the green bubbles with white text did not meet that threshold at the time, and it stayed that way for quite a while. And for all I know the light themed version of the app still does (I have mine on permanent dark theme).

In Japan (not sure in other countries), I went to the Apple Store. They said to complete the purchase, use the Apple Store app and scan this QR code on their device. I did and it immediately wanted me to share a ton of info with the main highlighed button "Share Now" and in small lettering below that "customize and share", where in you can see all the stuff they were going to take.
