PS4 Pro 4k enhancements?

I did a search and found nothing. Is there any word about 4K on the PS4 edition and/or enhancements? I am assuming the performance would be comparable if you were running on an XBOX ONE X?

Also can anyone tell me the difference between this and Age of Conan? Age is dubbed an MMORPG while this is survival, but from what I have seen has many MMO elements. Thankyou.
