At D-Day, I felt the bright yellow armband had little effect on my camouflage, and most of my kills were under 50'. There were instances where I had to wait until the enemy was almost 30' away before I could discern their armbands, other times I did not take a shot because I could not see the armbands of the other team. As many of my Axis teammates said, the color of the Allies' dark blue armbands definitely gave them an advantage, and I'm not 100% sure it wasn't a coincidence.
