The server knows which client you're using. There are indeed stricter restrictions for apps that come from app stores.
A lot of content in Telegram is moderated only for iOS, while still being available on other platforms.

And even then, I believe that only applies to users who haven't flipped the "Show 18+ Content" toggle in the app settings. (It's off by default.)
I don't think there is a "Show 18+ Content" in the app downloaded from the App Store, it's only hidden in the web app (activating it will also allowed NSFW content on the iOS app).
It's definitely there for me, second from the bottom in the "Data & Storage" menu. Maybe it only shows up once you've enabled that option from another app or something?
Yeah I think so.
Visible in my iOS app, was disabled (content hidden) but could be toggled on/off within the app.
Some channels are only available on android for off-play store apps, it is server side restriction of course.
