nah, not at all. i've been following rugby league pretty avidly for 30+ years and I don't think it is any worse now than it has been at any time over then. in fact, compared to the late 80s and early 90s it is much better. since refs have gone professional I think it has got better since they are obviously fitter, better trained etc.
since the SL war they have been pretty much at the same level. I don't really have specific memories of how they were every season but I certainly don't think they have been noticeably worse this season. Last year was actually pretty awful to be honest and so was the first year the NRL had two refs but this year hasn't been exceptionally bad in my opinion.
I think people just have really short memories and love having a reason to complain.
