I wouldn't want it to cycle through loads of near identical photos, or ones I accidentally took of the floor.
Further to the other answer: it also has algorithms to exclude photos like this. I’ve never seen it cycle duplicates and it attempts to leave out anything that’s wildly out of focus or just a big patch of one colour. Admittedly I tend to delete such photos anyway, so I don’t have as many, but I’ve never seen it show anything totally crap.
