It doesn't seem we'll be able to catch a break any time soon, more games have received an Xbox One X update since yesterday, so here is more coverage in super high quality. Forza Motorsport 7 looks way cleaner than before it was patched, while Rise of the Tomb Raider offers several choices to choose from (some of which do not go without a few framerate issues). We're not quite sure how Dead Rising 4 benefits from the patch it was given, but whatever it is, it does not make the game look especially better. Framerate may be smoother overall, there might be a small bump on resolution over the original release, but we don't know exactly. The game is HDR compatible now though.
Note: Except for the Forza 7 video and the first 2 TR videos, the footage we posted has no sound due to a technical issue we didn't spot before recording.
