Simple Q&A for Pathfinder 3: Find With a Vengeance

[Da'Shain]

Q 263

Does the effect of Spell Specialization apply to Dispel Magic? The text of the feat says that it adds +2 to CL "for all level-variable effects of the spell." Is the dispel check a "level-variable effect"? Or is it simply a means for attaining a binary effect (works/doesn't work) which you can affect the chances of?

EDIT: Same question for Gifted Adept, which has the slightly different language that when you cast the spell "its effects manifest at +1 caster level." What counts as an effect when we're talking about Dispel Magic?
