I'm sure you are right although one of the aspects of "digital" lenses apart from anti reflective coatings is to improve the angle of the light striking the sensor. I also recall reading what I said as well (in Amateur Photographer I think) complete with diagrams showing the front area of the micro lenses larger than the rear area so increasing the light gathering power. My mind just boggles at the thought of being able to manufacture the filter with millions of little lenses!
