Store Preview Videos -- Fallback Resolution?

App Store Connect requires four different screen resolutions for preview videos -- full screen iPhone, home button iPhone, iPad and Mac. Will the app store display the video for a different device than the device the app store is viewed on? For example, if I create only an iPad video, will it display to users browsing on an iPhone?

Or do I really need to record and edit four separate versions of each video for all users to see it?
