I didn't really notice until I saw that video, personally I don't really care or expect perfection on a 3.2 inch screen. I mean its like expecting a cinematic experience watching a movie on an iPhone. Its just not going to happen.
I would also expect a true professional to be able to compensate for this with just a little bit of time working with his/her camera. I for one don't really even look at the screen all to much other than occasionally looking at composition or if I'm looking at the histogram. But then again, I'm just an enthusiast.
