There is a rule.
"A creation spell manipulates matter to create an object or creature in the place the spellcaster designates."
But that rule only applies to objects and creatures.
It is inapplicable to the discussion at hand.
Who is changing RAW now?

If we make the wording in the subschool description consistent with the wording in the school description - that is, replace 'objects and creatures' with 'objects and effects' - the inconsistency goes away.
And creates an even worse inconsistency. Orbs are both magical and non-magical when they hit their target.
Compared to the lack of conjuration creation energy rules, that is a pretty big inconsistency (in fact, I do not really see an inconsistency with Conjuration Creation and its spells as much as I see a missing rule).
Not only that, but replacing "objects and creatures" with "objects and effects" drops creatures from the Conjuration Creation school completely. You are
adding a new inconsistency for Phantom Steed to resolve your (supposed) inconsistencies for non-object conjuration creations (which can be easily resolved by just realizing that there are no conjuration creation non-objects non-creature explicit rules).
And even if one changes the general conjuration creation rules to objects, creatures, or effects (by cumulatively adding the Conjuration School rule with the Conjuration Creation Subschool rules), it still does not imply that one should change the instantaneous conjuration creation rule to objects, creatures, or effects.
So, even doing it for the non-instantaneous cases (31 out of 33 of the rest of the spells in the PHB) does not mean that one should do it for the instantaneous cases.
In fact, the easiest way to resolve your inconsistency is to just claim that the Conjuration Creation spells in the book are Conjuration Creation spells. Period. End of story. No need for the instantaneous energy one in the PHB to match the object and creature rule. That's a rules change.
It's pretty obvious that WotC never considered allowing Orbs to bust through AMFs, or they would have mentioned it somewhere. Hence, I consider your position on this to not match RAW nor match designer intent. It appears to just be your preference and has nothing to do with rules at all.
When we add the fact that Conjuration Creation Instantaneous spells just flat out should not create (more potent than Evocation) Energy Effects (and many people agree that WotC foobared on this), it just seems nonsensical to change yet another literal RAW rule to make Orbs even more potent.
