I think you may have missed my point.
The momentary flare created by a Sunburst spell cast in circumstances of natural darkness will be visible only if we accept that the spell - however temporarily - dispels that darkness.
That's a strange logic. Natural darkness isn't something that exists of itself; it is the absence of light sources. Sunburst is, very briefly, a light source, but it doesn't dispel the natural darkness, because there's nothing to dispel. Instead, it changes that unlit dungeon into a lit dungeon.
(Cf. a spell which creates a momentary depiction of a flaring light - that will not be visible in circumstances of natural darkness, no matter how lifelike the depiction is - but such a spell might nevertheless have the power to dispel magical darkness.)
Now that is a very interesting statement.
