PoS Quest Rewards Pre&Post Buff [Questions]

[Baler]

Question for those Plane of Sky knowledgeable, Trying to improve the wiki.

Plane of Sky Quest rewards get 'buffed'?
And during which Era does this happen? (Hole Era?)
Do all PoS quest rewards have a buffed version?

Here is an example:

Post-upgrade PoS quest reward.

Are these what is currently on green?
The pre-upgrade to my example?
