The OpenShift icon in OpenShift product logos has been deprecated in favor of the Red Hat fedora. The product logos need to be updated to reflect the new brand standard.
There is a follow-on PR to update change the Azure Red Hat OpenShift logo to the generic Red Hat OpenShift logo: https://github.com/openshift/console/pull/4954
Additional PR to change logos for oauth. https://github.com/openshift/cluster-authentication-operator/pull/266
Logos are all using correct standard ones on login page, top-left of banner and About overlay panel. Verified on 4.5.0-0.nightly-2020-04-09-231931
