Unfortunately the app doesn’t know if you have set that (or for that matter if the originals have all been downloaded – you could set that and then it could take hours or days for them to appear). I am uncomfortable with the app having a feature that only works for some people sometimes. Here is another example. You search for exif and save a smart album. That album syncs over iCloud and on your iPad the results are different / incomplete. There may be a solution but it’s fraught with complications.
