To expand on SrMi's explanation, there are several ways in which data is stored in a DNG file.  Much of it is tagged information, specified as part of the TIFF data standard from the late 1990s.  EXIF topls can read that.   Some of it is manufacturer's private data, which can only be read if your have a contract with the manufacturer, as it is encrypted.  You won't get to see that.  Then there is an intermediate class of XMP tags, which are filled in to Adobe's specifications, not encrypted, but not standardized either.  Adobe and Leica seem to have created some of these for the perspective frame definition. Some tools can see them, starting with a text editor.  They contain the pitch and roll angles that the camera measures, and the four calculated corners of the PC frame, plus a few more tokens which Leica and Adobe have agreed on to specify how the image is to be handled.  Those are not all that mysterious, but other companies may have to speak to Adobe to ensure that they understand what they do and are kept informed of any changes.

Thanks for the clear explanation. Is this the same as Adobe Upright?

I use Capture One, so I don't know which is clearest names to use in describing the set of actions that let you apply this or modify it.  It's in the Geometry dialog.
