nVidia driver package question

I am confused about the nVidia driver package. I thought it was a “regular” package. I added the nVidia repository with zypper and installed it. Later, it was upgraded by zypper from version 450.57 to 450.66.

However, I was dealing with a problem in another application that I had installed as a Flatpak. When I ran “flatpak list”, the output says that the nVidia drivers (both versions) are flatpaks. This was a surprise to me. Is it correct?

Here is the flatpak command output:

GNOME Application Platform version 3.36         org.gnome.Platform

What about the output from;

zypper se -si *nvidia*

Flatpak packages are completely distinct from RPM packages (zypper). The nvidia flatpak packages exists so sandboxed apps can access the GPU, the user-mode part of nvidia needs to be available inside the sandbox as well, and they need to match the nvidia package in the host system.

Thank you, @awerlang. That makes sense.
