I don't know if this is iPhone specific, but all photos I shoot are in RAW and edited in Lightroom CC Classic (for home edits) and Lightroom CC (for on the go).
Here is Lightroom CC Classic (excuse the poor edits, I'm just beginning to rebuild some lost presets).

Notice on export, I use all Metadata excluding personal and location info (as if it'd matter for this photo because the camera has no GPS).

And here's a photo I took on my Galaxy Note 9, edited in Lightroom CC. While it doesn't appear to have the option to export metadata, it does it anyway.

I'm unsure which software you're using and whether Apple includes these in their files, but I wouldn't doubt it's not in shooting RAW. You just need to find the option to export the metadata and it'll display correctly.
