Apple’s decoder does not read that information. The other (larger) apps sometimes read that data and get help from the camera manufacturer to process the image.
I am not aware of Photomator doing it since it also uses Apple’s decoder. It’s possible that they read a few fields – can you tell me specifically what they can read?
Karl’s comment about the LUTs is also valuable – I have some Fujifilm simulations in Nitro (they are not official – I made them by hand).
