I think that high contrast areas come forward visually and neutral areas recede. The light flower petals against their dark reflections are high contrast. When the frame is even a stronger contrast ( black and white) it competes with the flower and pushes it back visually. With a more neutral frame the flower comes forward viusally giving it a sort of 3-D effect. One would almost think the flower in the edited version is larger but they are exactly the same size.
