iPhone 14 Pro: can't shoot photos at 48MP

Hi Apple Community,

I have just received my iPhone 14 Pro.

I can't shoot photos in 48MP though. Did I miss something?

I went to Settings>Camera>Formats>Apple ProRAW.

I checked Apple ProRAW and choose 48MP resolution.

Back to the Camera app: I made sure "RAW" (upper right corner) wasn't dashed.

I took a picture of my room: the info panel say the photo was taken in RAW, with the main camera... in 36MP (8064x4536 resolution). I didn't use the zoom (x1).

I can't figure what I have missed... but for sure, I did miss something!

Can you help me?
