Well, this is weird. I looked in DPP and I can't find it any longer. And I swear the info was there. In October 2020 I asked if the shutter mode could be somehow saved in the exif. I could see it in DPP but as I had to convert the raw files to DNG's the info was lost. Here's the comment:

By the way, is there a way to see if an image was taken with the ES or MS? In the exif I mean. DPP has the info but I have to convert the files to DNG (old system) and no other app I have includes it in the exif.
So either it's a setting somewhere or it's not included anymore with the R7. I've looked for R6 raw files from 2020 but I have none, everything is DNG. Maybe somebody can try looking at a file from the R5 or R6 from late 2020?
I was and am running version 4.14.0 on my Mac.
