As you can see in (3.,) the search finds srcpackages only. It looks like the binary (.rpm) packages are not provided by your repos. If those are typical SLES isos, it's due to the way they are built.

• SLE-15-SP4-Full-x86_64-GM-Media1.iso contains an empty rpmmd repository in it's root. That's why you see no binary packages.
• SLE-15-SP4-Full-x86_64-GM-Media2.iso contains no repository at it's root. If there are no repo metadata zypper assumes this is a plaindir repo. I.e. a collection of .rpm packages without further metadata. Zypper recursively scans the directory and collects all the packages it finds. Media2 contains the sources, that's why srcpackages were found. But actually the source repos (if needed) should be set up the same way as the packages.

If you look onto the iso, you'll see that it in fact contains multiple Module- and Product- repositories located in subdirectories. These repos contain the actual packages you are looking for. You need to pick the repos you need.

So you don't want to add the iso's root directory iso:/ as repo, but e.g. the iso:/Module-Basesystem: zypper addrepo iso:/Module-Basesystem?iso=/home/images/SLE-15-SP4-Full-x86_64-GM-Media1.iso Module-Basesystem
