Atmos output from iphone to Apple Lightning Digital AV Adapter?

Hi, I am trying to find out if it is possible to experience atmos tracks from Apple Music, from my iphone to an atmos soundbar.

I don't have an Apple TV box.

I have an iphone SE 2020, which gives the atmos option within settings, LG atmos soundbar which I am about to set up, and an apple lightning digital AV adapter. I will use the soundbar with an LG OLED TV that supports atmos.

My question is will the atmos metadata be output through the AV adapter HDMI port so that the soundbar can receive it?

Thanks
