I'm sure the surfaces reflect differently. You're really trying to answer the question of whether or not it matters...
I think it doesn't. I used to be a stickler about having white surfaces as near my plants/lights as possible to maximize reflection. Then I started to think about it more. Sure, if you're going for 100%, you have to do it, but is it worth it? Look at the distance the light has to travel to get to the plant via reflection. By the time it gets there, how much energy does it have? It's an inverse relationship to the distance, so it gets weak REAL fast.
Now let's add in the effect from the reflective surface difference. How much of an impact do you think this will make? I contend the distance has a far greater impact, so the surface becomes insignificant.
Of course... I'm probly wrong
Looking sweet in there Ronnie. Is that tray in the veg closet just to catch run off?
I had my hydro shop get me 2 2'x4' trays. I'm picking them up this weekend.
Of course I plan to actually flood and drain mine
Very nice set up, Ronnie. I'm looking forward to this shoot-out!
Hey Crawdaddy, yes one would think more red is better for flower but I know blue light is more energetic than red light (higher electron volts) and also blue diodes more expensive to produce. but your right we'll know for sure in a few months.
going to wait till the clones have rooted up enough I'm sure they will transplant well.
Subadub dub!
Congratulations Ronnie! 
My money is on the Blue/White for veg! I had my ZNET designed with extra blues. My clones didn't like it under the LED. Too strong I think. I wait for them to get established well before I put them under LED.
Intense set up! I can't wait to watch this grow in action!
Coming late to the party. Catching up....
