For Spatial, it isn't just about what plays it but also what surround encoder was used to make the content. See if you can find a trailer with Dolby preferably Atmos in the Apple TV or iTunes Store app. It is also better on an iPad since you can move your head and the audio space will follow.I am actually using iTunes ONLY to get files onto my phone ... video for VLC and flac for an app called VOX ... have not used iTunes for music in ages ...
Can;t really do streaming since we have very limited internet on this island and music can eat up quite some when in higher Q ...
Got the new FW on APP, can;t say I hear a difference yet, need to some time ... no idea how to test spatial audio, seems you have to use video files from whatever apple proprietary source (itunes? apple TV?) i might be locked out there because of region again .. never got anything 'official' from iTunes store regarding video ... maybe they have free trailers? Shall test
You should also check out the Accessibility->AirPods->Audio Accessibility Settings->Headphone Accomodations... to see whether the simple customisation works for you. Note these customisations follow your around on playback on iPad and iPhone but not Mac.
