i would say: No, not more limited. Rather the same functionality with different GUIs: The classic Endpoint Dashboard is completed by Logs and Events in other Dashboard views, while in Infinity portal Harmony Endpoint Logs and threat Hunting is combined wit EPS policy and computer management.
But with Cloud Management you get both at once - you can use the EPS Dashboard on a Win10 client for blade configuration the old school way and at the same time use the infinity portal for easy monitoring and other tasks !
