Is this normal with SEP 12.1.6 MP5

Hi guys I just did the installation for SEP 12.1.6 MP5 today and updated it with the latest protection definations. However I noticed a strange thing that when I exported an installation package with all feature set and all content ( with full definations) the exported package size was only 286 MB, strange isn't ?

For earlier versions i.e RU6 MP5 and below I remember the package size used to be 600 MB+ with full content so have something changed in RU6 MP5 recently?  Attaching the screenshot

Thanks
