I've been following this thread and yesterday I was able to get my hands on a 13 Pro. I've been testing it against my 12 PM and honestly I can't see any difference. The post processing that Apple is doing to the JPEG/HEIC files is slightly different, but once you switch to ProRaw they look about the same.
Here's a comparison between the 13 Pro, 12 Pro Max and a full frame camera using the Sony 24mm GM (which is as sharp as it gets for this focal length). If anything, the 13 looks slightly sharper.
These are all ProRaw/Raw imported to Adobe Camera Raw with default settings and sharpness set to 0 (
