About necromancy - Undead Thrall feature

[Kamuizin]

I asked this question a long time ago, but so many patches happened, thus here i am again:

Undead Thrall has 3 features: (i) Animate Dead, (ii) Additional Undead and (iii) better summons.

I already confirmed that Animate Dead and Additional Undead, the first for obvious reasons, affect only the 3th spell circle Animate Dead.

But better summons have a contradictory text, between 5e and BG3:

5e Text
Whenever you create an undead using a necromancy spell, it has additional benefits:
The creature's hit point maximum is increased by an amount equal to your wizard level.
The creature adds your proficiency bonus to its weapon damage rolls.

BG3 Text
Creatures created with Animate Dead have additional hit points equal to your Wizard level, and your Proficiency Bonus is added to their damage.

So, did this is just a mispelled text and the feature work as intended in 5e? Or for BG3 Undead Thrall - Better Summons only affect Animated Dead Spell?

At 13 sep 2023 a comment in Fextralife confirmed that Better Summons only worked to Animate Dead, it's still this way nowdays?

Bump.

By the way, a new question: Is hit/roll chance of summons based on the summoner proficiency be default? Or it's entirely based on the creature data?
