Were any third party games at E3 confirmed to be native 4K on XBOX?

Now to get higher resolution but still not True 4K you will have to pay $100 extra over PS4 Pro.

$100 extra give you:

True 4K (this might be a lie you will get better 4K) *(only true for some games, so far most arnt)
Better performance *(most games run capped fps, locked to 30, so not nessarily true)
Faster load time *(we dont know, dont have any games to messure one vs the other yet)
4k Blu-ray player *(true)
Xbox Game pass and EA Access. (EA access 40+ & Game pass is 100+ so, $14.99/month over 140+ games) <-- This is great for new comers.
Access to largest gaming library running with improved performance. (Xbox 360 & XBox games) <-- This is not for everyone but I love this feature. 

EA access is meh imo.

Access to largest gaming library?  PS4 has like 1750 games to the XB1 1350. ?
