That strongly depends on the country. In the USA, probably. Here in europe there is no problem showing naked breasts in the evening news, when relevant.
However, the US finds mild nudity the most offensive thing ever.
Back on topic: unfortunately Apple applies its US based rules on all content worldwide: I know an app by a huge broadcaster that got rejected based on nudity in an item on, I think, breast cancer. Which is no problem here at al, to show on national TV.
keep in mind that on a closed platform you need an approved app to access the web. If a closed platform like iOS would reach a dominant market share then the web would be an easy target (and a natural competitor)
