Higher detail and/or framerate, but it will probably be noticeable almost only in exclusives (so a direct comparison with the same game on another platform won't be possible) or if devs will be willing to put some additional efforts and resources in tweaking each version of a multiplat.
In most cases the improvement even of the weakest from the previous gen will be far greater and noticeable than the differences between two 8th gen versions.
