Compare the width of the pinhole lenses in the 13 pro to the compacts - it's a fraction of the size. That forces the fixed focal length, but can't get past the limitations of that size.

Also, while the wide angle camera of the 13 pro pairs with a larger 44mm sensor (versus the TG6's 28mm, that 6x lens has to be paired with a 12mm sensor to get that effective focal length.

the iPhone has a wider aperture, as far as I can tell at all focal lengths. To the extent where it’s gathering more light throughout even taking sensor size into account, as far as I can tell.

You have to be more specific with that statement.   A lens that is 2mm wide cannot collect as many photons as a lens that is 12 or 20 mm wide (I don't have a TG, so I can't estimate how wide it is).

There's also a long running problem with figuring out what f1.7 actually means - actual vs 35mm equilivancy.
