Money, first of all you haven't scientifically ruled out anything from effecting the dice. You have so many variables stacked up, you can't even prove which are effecting the outcome and which are not. In order to prove or disprove that only the shooter is effecting the dice, you have to rule out EVERYTHING else. That means table, felt, people, air conditioning, chips, throwing style, setting of the dice, and I do mean everything.
I would first see if you could green screen the dice as they are being tossed by the shooter. Use a number of various shooters and see if that makes a difference. However, they must all toss the dice the exact same way each time in order to have the best results. Then, I would make a perfectly flat surface, and repeat the first exercise using the same people. Your going to have to do this several hundred times adding just one additional thing in the mix until you get to a typical craps table. Its the ONLY way to prove or disprove anything, there's just waaay too much stuff to knock out first. Then and ONLY then can you say anything scientifically about what effects the dice at a craps table.
