I think it really depends on the nature of your fish. With a lot of ground cover like small pots and IAL leaf matter maybe the shrimp can hide effectively.
FYI, Fred used to ignore the 2 amanos. Then one day he decide they were fun to "play catch" with. Thankfully I had a driftwood that the shrimps could hide out. They did not come back out until Fred left the tank for the QT tank.
So yes, even with a lighter color Amano, they are still vulnerable. I cannot imagine having a colorful shrimp in the same tank....
