Before judging the screen, we should understand the reasons why they are like that. Actually they aren't bad screens at all. They are different and there are few reasons for that.
The Latitude D-series is designed for business use and so are the screens too. Those screens are made with the new Prism LGP technology and there are few things how they differ from the screens made with ordinary technology.
It's good to read this whitepaper to understand the issues with these screens.

One of the most valuable feature is that they are more than 20% brighter than traditional screens when compared with similar backlights. So they dont need as effective backlights to be bright enought for business use. That means more battery life which is very important in business machines.
I personally where little disapointed with my screen at the first place. It wasn't quite as nice as the screen in my previous laptop, but the previous laptop was optimized for gaming and entertainment, not for business use and battery life. Now, after I understand the benefits of this new technology I wouldn't change it to anything that consumes that much extra of my battery life. I also do like how it looks more and more every day.
As a conclusion after almost 2 months of using it I would say the screen is good for everyday use and very good if not excellent for business use.
