Another update on how genuine the contents of this archive are. I obtained a
copy of MS-DOS from another source. Sadly not my floppies which have become
unreadable after a mere few decades in a garage and ran diff over the files
in the images. Floppy 2 and 3 files are identical but there is one single
difference on floppy 1:
diff -urN /mnt/AUTOEXEC.BAT /mnt2/AUTOEXEC.BAT
--- /mnt/AUTOEXEC.BAT 1990-02-03 14:00:00.000000000 +0100
+++ /mnt2/AUTOEXEC.BAT 1995-03-01 21:57:12.000000000 +0100
@@ -1,4 +1,4 @@
@echo off
nlsfunc
keyb gr
-setup
+rem setup
So the call to setup has been removed from autoexec.bat. All MS-DOS
distribution media I've ever used were booting straight into the installer.
Also note the file modification date which for the modified vetusware
version is from 1995 while the other image is from 1991. This means the
vetusware ersion is not genuine. FYI, even MS-DOS 6.22 was release before
1995.
Yet the images of floppy 2 and 3 are not identical. So I went for the deep
die and compared the hexdumps of all three floopies from both sources. I
found that in addition
- the volume serial numbers differ between the two sources
- all file modification dates differ. On the vertusware version they are
from 1991, about one month before the release date of MS-DOS 5.0. On
the alternate source they are a good 14 months older, from 1990!
So these differences are pretty benign and I don't know what to make from
the differing file modification dates and volume serial numbers. But the
autoexec.bat modification clearly is not genuine. So the vetusware
version is not as squeeky virgin as claimed.

Update: I compared the images to images from another source and they are not identical. I have no idea if that's to be expected with Microsoft releases or not.

This is the same zip file as https://vetusware.com/download​/MS-DOS%205.0%20German%20editi​on%205.0%20DE/?id=6863 which claims to be the German MS-DOS 5.0 version. A /very/ cursory check finds German strings in the image of the first file so this indeed seems the German version of 5.0.

And another...
The description promises "5 x 360 KB images".
In fact they are 3 x 720 KB images. :(

So called "untouched"... what a joke!
The uploader is faking and wants to show off!
Not many title their uploads as "untouched", even the images are.
The date of the autoexec.bat on disk1 is from 1995(!) while the OS is from 1991. Pooh!
And that's not enough... this file is not just touched, it's even modified ("REM" before setup).
"UNTOUCHED" wow!
Setzen, 6!
