There is probably a better way of answering this but here are my two cents.
The short answer to your question is yes, splunk ES contains all features of splunk enterprise and additional advanced security features. We can't do proper comparison between ES and splunk enterprise because ES is a fully fledged premium application designed around event correlation, management, and response while splunk enterprise is a software where you will install ES.
