If the rings are only slightly worn, there will be oil caught in the combustion chamber, but as you said, it is not much oil so it wont be visible during hard throttle.

Once you start to engine brake, the oil will actually be sucked off of the cylinder walls and burn up in the combstion chamber, becoming visible.
