On macOS, root does not matter much as every user who is an administrator works with the same power. When you enter an administrator user and the administrator password in a permission dialog, any user (even a non-administrator user) does.
Some apps have a script or framework to change ownership to root, others do not change it (like when you copy an app from Downloads or a disk image)
The information you display makes no difference in terms of security. These are just permissions to a folder and package that anyone can read and execute. Other mechanisms check for known bad software and confirm that parts of the application have not been tampered with.
