There are no RHEL specific features.

  Au contraire, there are and they're quite valuable their enterprise customers. The most important is the detailed security errata published along side their RPM packages which are necessary to do things like "only install security updates" or "check if any packages have upatched vulns." RHEL but not CentOS also come with security/regulatory profiles like STIG which are necessary to run in certain environments like the DoD. Red Hat also has a license to distribute Oracle Java that CentOS lacks and so it's not available in their repos. They also ship with the Cisco network drivers that CentOS again doesn't have a license to distribute.

    There's also the extended support for minor releases. With RHEL, it's possible to stay in a minor release for longer while in CentOS you always have to migrate to the next minor release. For instance, according to the graphic at the middle of https://access.redhat.com/support/policy/updates/errata https://access.redhat.com/support/policy/updates/errata with Extended Update Support one can stay at RHEL 8.2 until the middle of 2022 (so RHEL 8.2 has a full 2 years of support), while with CentOS, you had to migrate to CentOS 8.3 this month if you want to keep receiving updates (so CentOS 8.2 had only 6 months of support before being replaced with CentOS 8.3).
