I watched it about six months ago, I guess. I remember being struck by the incredibly beautiful color and perfect contrast levels. I wasn't looking for sharpening/grain smoothing, so I might have just overlooked it because of the incredible color. My personal tastes put priority on overall balances over fine details. It's actually easier to find sharp, clear blu-rays than ones with really good contrast/color.
Also, I think my projection system might be doing some sort of cleaning up of sharpening artifacts. I stared at the UK Zulu over and over trying to figure out what people were complaining about, and I couldn't see it at all. Netflix HD streaming looks fantastic projected.
The only films I can think of (besides the obvious Disney ones) that bother me when it comes to grain smoothing are Evil Dead II and Texas Chainsaw Massacre.
I bought the second re-release of Evil Dead II, it's supposed to be better than the first release, i haven't watched it yet, hopefully it's a huge improvement over the first release, i don't think it's possible for a projector to hide sharpening halo's, it's there and on the transfer, some people are immune to seeing them, it's possible you are, unfortunately i had to train myself to spot such issues when i started my website and the downside is that i spot them easily now and they tend to take me out of the film.
