OpenShift is Kubernetes, just like RHEL is a Linux distribution with support for enterprises. OpenShift makes an opinionated choice about what they bundle (distribute) with vanilla Kubernetes. For example, Istio was chosen as the service mesh distributed with OpenShift 4.

I agree with you here, but do think it's worth pointing out that OpenShift adds some non-trivial features to Kubernetes and they aren't just plucked from existing projects and bundled. Some major K8s features started out as OpenShift features and got merged upstream (Ingress, Deployments, etc). Red Hat innovates and improves the distribution rather than just repackaging it and slapping on a support contract.
