"5. Theme — purely visual styling (“look-and-feel”) for a component."
Bootstrap styling contains styling as for layout, components and look and feel, but mostly it's used to unify look and feel of the whole web application (core and any modules and custom modules).
Bootstrap theme is designed to override look and feel of any components which follow bootstrap class convention, so it's supposed to be loaded under "theme" in global-styling of libraries.yml
If you're using sub-theme (example theme/custom/my-bootstrap4/) derived from Bootstrap4 - sub-theme should override theme/contrib/bootstrap4/style.css with its own - Drupal should not be loading both style.css from contrib and custom as sub-theme is self-contained, fully re-compiled customised styling.
