I heard a rumor and didn't see a question about it. So here you go :D!
If I may, when a Pokémon is bred from a luxury ball, it's offspring will also be contained within a luxury ball, which leads to that Pokémon becoming more friendly more easily. I hope this clarified what you were looking for. Have a wonderful day.
When a Pokémon is hatched from an Egg, its value is set to 120. -Bulbapedia
The Description of a Luxury Ball :
A particularly comfortable Poké Ball that makes a wild Pokémon quickly grow friendlier after being caught.- Serebii
I don't think Hatched Pokemon qualify as Wild Pokemon.
