Chinese consumers do care about iOS vs Android. It's just that the Android ecosystem has been much too horrible in China (Play being blocked, big-name companies have their own "app store", affiliated apps keep waking up each other in background to increase DAU). Those problems go away automatically if you pick iPhone.

The best-selling Android phones in China (Oppo/Vivo, Huawei, Xiaomi) have this horrible problem in control, by providing their customized Android with aggressive permission control, background apps cleanup etc. This also closes up the gap between iOS and Android without Google's presence.
