I had actually believed it was watered down because I heard so many arguments about how the time dilation wasn't used.

But thinking harder on it, this might not even be the case.

Maybe Itachi was set to keep Sasuke in there for 3 days like Kakashi. Maybe Sasuke just broke out before the "Tsukuyomi time" was up.

Itachi could have very well been using time dilation. We just saw Sasuke break out of it and the aftermath of it. Sasuke probably just broke out of it before Itachi finished the Genjutsu.
