This really isn't noticeable unless you have very fast objects, or very low frame rates (sub-20fps). As long as you intelligently choose your occluders and conduct some simple tests to identify the above, there shouldn't be any problems.
In what context, culling or special effects? Culling has to be conservative otherwise objects get culled that shouldn't be. If you are having to be overly conservative then you are also not getting the most of the potential culling. One has to be very careful about making sure the benefits you gain outweigh the costs involved, if you are loosing efficiency of culling then the cost benefits shift against you. Personally I'm pretty skeptical about using occlusion querry for culling in anything other than quite specific apps. For special effects things are much less critical. For special effects like lens flare one has to use almost the whole scene as occluders, with lens affect as post process.
