The dummy data import option from the Import/Export tab of the theme options is not an exact copy of the theme demo but one that is very close. Some of the images and video are not allowed to be redistributed and so it isn’t included. In case you’d like to buy used stock materials separately we do provide a full ID list for images. Feel free to ask for it.
With each feature update the dummy data is updated to include an example of the new feature(s) and we will continue to update the online documentation with examples and how-tos.
