From Artifactory release 7.46.3, you can see the scope of a token in the Access Tokens UI as a column called Scope.
From Artifactory release 7.89, you can see tokens generated by Project Admins. A token generated by a Project Admin will contain project permissions and have a Project Key value and a Project Role value. It will display a value in the Project Key column whereas for non-project admin tokens the Project Key will be empty.
