I have noticed this exact thing with my bags. I have noticed this difference between French-made and USA bags. The French ones have had a slightly more structured feel to the canvas and a lighter brown and less vibrant LVS than the USA canvas. The USA canvas is softer and shinier too. This has been consistently true for every French and USA speedy that I've ever had, and I've bought and sold a lot on ebay because as soon as I find a flaw on my bag it has to go! I've had them all authenticated at LV so I know they were all authentic. Now, I actually have one that I bought on ebay to use while mine was being repaired at LV. This one is from 2001 USA and the one that was being repaired was 2007 USA---big difference in the canvas. The 2001 USA canvas was like the French canvas----I believe it's different batches depending on what they are using at the time in different factories. I love how these little differences make our bags unique though!
