Over in the
Digital Foundry analysis thread I posted some extensive notes on upgrades (and a downgrade) that they missed. They're not directly appropriate to your concern since they're about PS4 improvements rather than specific Pro ones. But some folks might be interested in the enhancements
Zodiac Age features.
That's correct, yes. The "red x" modes are only available when hooked to a 4K display.
It means the mode marked with an orange dot is what 1080p screen users get automatically. Users with 4K screens generally do have to force it with PS4 system settings, rather than within the game.
What may be confusing is that each row in the list is a separate mode. If a game only has one Pro row, every user gets the same results (with downsampling if they're on a 1080p display). If there are multiple rows without x marks, then every user can choose from among different modes (with downsampling where appropriate). If there's multiple rows with x marks, 1080p users are locked out of those.
That's right. In fact, at 1080p it has better AA than when run on a 4K screen. That, coupled with the fact that it's only 1440p in high-res mode, means that lack of downsampling isn't very noticeable for this particular game. It may even be preferable. This is also true for titles like
FF XII, The Witness, and others. Of course, giving users an option would be best.
