I think the difference will not be that the Dutch state won't appear if Spain has a good policy or if dutch provinces are catholic but that it will appear even if Holland is French, English, or even part of a calvinist HRE state.
It can be a specific event or a generic one (a very rich province without a powerful local nobility revolt against a foreign ruler to form a republican state), but the conditions for the Dutch revolt and independance would probably be met by any foreign ruler.
Before being spanish most of dutch provinces have been french and, far before calvinism, revolted a dozen of times against french kings (including support to the english in the beginning of the HYW), then they supported Louis XI against their duke of Burgundy, refusing war taxes, then they asked to be given to the emperor and not France to be part of a less centralized kingdom. They were always against their successive foreign rulers, giving hommage to new powers only to strenghten their independance. If something was written, is the result of a long history and a real national feeling, it's the dutch independance, and calvinism has not be the main trigger.
