Hold your horses buddy, you’ve gone a little too far, TV+, Disney+ support spatial audio, Netflix doesn’t, you might try HBO MAX, seems to also support, don’t have any possibility to check. Also there might be some implementation problems. Seems that Spatial Audio enforces the use of some audio codecs, like AC3 5.1, or others AC3 based audio codecs. You can try for yourself converting any MKV to m4v (sometimes it’s enough to just copy the video track and conver the audio, but audio needs to be in AC3 5.1 or higher), then you can move the m4v file to the iphone or ipad using itunes and it will play fine using spatial audio. So while it might be possible for Infuse to implement it, they might only do this for supporting content (having the right audio track compatible with Spatial Audio) or a little harder, transcode the audio track on the fly. Either way, Firecore is looking into this, that’s what I’ve heard from their guy on twitter.
Lastly, saying that Netflix is Spatial Audio compatible is a lie, please don’t come here spreading lies
