Sorry the Featured Image is not different on search results. All Featured Image through out the Site are same. Like the post have same Featured Image in the category list also. (Category – Oculus). It’s not the Site logo but that posts also showing the same image that is used as Featured Image. But the Featured Image has used as Site logo with background.
And Premium Version also don’t have the feature to set different Featured Images on different Pages like Search Result Page.
Thanks
