What is "display file" in Windows and how it differs from metafile?

Question

Windows has long supported metafiles, a special graphics format for storing drawing commands. I won't go into this topic further; if you are interested - please refer to the Wikipedia article linked.

But GDI also has one more "file-y" format, called "display file". The only reference to it, without any details about, is in the documentation for the GetDeviceCaps function:

TECHNOLOGY - Device technology. It can be any one of the following values.

DT_DISPFILE	Display file

The only thing I could find in Google that directly relates to this is a similar question from 2000 from the comp.os.ms-windows.programmer.misc group on Usenet, which remained unanswered: https://groups.google.com/g/comp.os.ms-windows.programmer.misc/c/u0pKxmk8zEI/

Looking at the term "display file" itself, I was only able to find this article from 1979, where they are mentioned as a synonym for metafiles: Device-independent intermediate display files.

So, my best guesses at the moment are:

• it's the same thing as metafile, but device-dependent;
• it's a special type of metafile, tailored specifically for display devices.

Perhaps somebody knows more?
