How "transparent" is transparent mode in ASM?

I agree with Jim. Transparent term is misleading. It should be "non-blocking" or something similar, in my opinion. Transparent gives the impression that data is not being transformed by ASM at all - which is not true. TS cookie is being inserted, sensitive data might get masked (if DG is enabled) and Javascript challenge might be added to the response (if fingerprinting options are in place).
