Verified with OCP build, 
$ oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.3.0-0.nightly-2020-03-01-224924   True        False         64m     Cluster version is 4.3.0-0.nightly-2020-03-01-224924

$ oc get events -n openshift-kube-apiserver-operator | grep 'https://etcd-'
77m         Normal    ObserveStorageUpdated               deployment/kube-apiserver-operator             Updated storage urls to https://etcd-0.....openshift.com:2379,https://etcd-1.....openshift.com:2379,https://etcd-2.....openshift.com:2379
+                                                         string("https://etcd-0.....openshift.com:2379"),

+                                                         string("https://etcd-2.....openshift.com:2379"),
            "storageConfig":  map[string]interface{}{"urls": []interface{}{string("https://etcd-0.....openshift.com:2379"), string("https://etcd-1.....openshift.com:2379"), string("https://etcd-2.....openshift.com:2379")}},
            
We can see there is no ‘etcd-bootstrap’ related etcd URL in events log of  openshift-kube-apiserver-operator.          

Another way, verified from test code:
$ go test -v -run TestObserveStorageURLs
...
=== RUN   TestObserveStorageURLs
=== RUN   TestObserveStorageURLs/test_etcd-bootstrap
=== RUN   TestObserveStorageURLs/test_etcd_member
--- PASS: TestObserveStorageURLs (0.00s)
    --- PASS: TestObserveStorageURLs/test_etcd-bootstrap (0.00s)
    --- PASS: TestObserveStorageURLs/test_etcd_member (0.00s)
PASS
