Using the screencapture CLI on macOS Sonoma 14.0 (23A344) results in a 72dpi image file, no matter if it was captured on a retina display or not.
For example, using
screencapture -i ~/Desktop/test.png in Terminal lets me create a selective screenshot, but the resulting file does not contain any DPI metadata (checked using mdls ~/Desktop/test.png), nor does the image itself have the correct DPI information (should be 144, but it's always 72; checked using Preview.app).
I noticed a (new?) flag option, -r, for which the documentation states:
-rDo not add screen dpi meta data to captured file.
Is that flag somehow automatically set? Setting it myself makes no difference and obviously results in a no-dpi-in-metadata and wrong-dpi-in-image file.
The only two ways I got the correct DPI information in a resulting image file was using the default options (forced by -p): screencapture -i -p, and by making the capture go to the clipboard screencapture -i -c. Sadly, I can't use those in my case.

I'd appreciate any pointers, Matthias
