It seems to me that when connecting a DAC wired to an Apple device, the sample rate matches. This explains for example the interest of using an Apple device as a wired source for Apple Music.I don't have Apple devices, so I have no idea how to help you in this case. Maybe Apple Music is able to set a connected DAC's sample rate, like in Morchingen's case.
Whereas with an Android phone, the Android audio layer is only bypassed by specific apps (like Neutron or UAPP for example) but not by the Apple Music app.
On the other hand, for Apple Music, the use of an Android smartphone is more interesting when you activate the BT Receiver mode on the DAP because in this case, you can use the LDAC codec whereas with an Apple device, the best codec remains the AAC.
