To follow up, the following message from the glass manufacturer has put my mind at ease:
"It is possible that BMW had a second supplier for glazing parts on the F01/02 model 7-series. Nevertheless, we (Sekurit) exclusively supplied clear glass with thermo-control reflecting interlayer or green glass with solar-control interlayer."
I suppose this means that 90%+ of all US F01/02's (non-760's, ActiveHybrids and special orders) were not manufactured with Saint-Gobain glass.
