Not a projection so to speak, but i'll note one particular issue with lighting. The nursery at Disneyland was massively brightened up in one of the major renovations from recent years. This room was previously lit with a much warmer reddish maroon hue, whereas it now has a much more cool white-blue appearance. But to make matters worse, this light also spills out into the first area of the London scene as the window opens and you fly outside. Casting too much of that bright white light on the UV painted props and murals. Washing them out, revealing too much of the building structure and breaking the illusion.
