I just want to relay my experience with this issue, as I have been jumping through hoops with this issue for over a year. My MPB's display has the same exact problem as the OP, two bright dots smack dab in the middle of the screen. I also have the dark "dirty" smudges in and around the same area. My display developed these problems 3 weeks after buying it back in Dec '07 (I have a 2.16 Merom MBP). The funny thing is, they literally just "appeared" and have gotten progressively worse over the last 15 months or so. The first 3 weeks I owned it, I rarely if ever touched it. It sat on a stand on my desk and I used it only for email, and surfing the web. Any way...
I brought it into the Apple Store (57th and 5th, NYC) and had a genius take a look at it a few days after the "blotches" first appeared. Being it was only a few weeks old and after hearing such positive genius bar experiences, I was SURE they would replace it at no cost to me. They guy took a look at it and complimented me on how "brand new" and "pristine" the machine was, opened the MBP and spotted the "blotches" right away. He told me he had seen these before and there was nothing he could do. He went on to say that if really bothered me I could pay to have the screen replaced. Needless to say I was pretty angry. I'm not the argumentative type, so I just expressed to him that I never used the MBP and it's absurd that I would have to pay for something that is obviously a design flaw. He apologized again, and handed me my computer.
I didn't really know what to do, so I just made an appointment at the other Apple store here in NYC (SOHO store) hoping maybe I'd get a different answer. I took it there and got pretty much the same answer. This time the guy tried to massage the blotch out, and told me to try and do the same when I got home. This time I asked for a manager, which made me feel awkward because the guy was really cool and I didn't want to come off as a jerk. Spoke to the manager, who deferred to the genius most of the time as I was explaining my situation. She told me that there was no way she or Apple could replace my screen unless I choose to pay for the whole thing. Dejected, I just took my computer and left.
I decided to just put up a black desktop wallpaper and just forget about it, until recently. I started to google around and found that other users who were experiencing the same display malaise were getting their screens replaced by Apple! Why all of a sudden are they NOW starting to consider this a design flaw?! It's been about 15 month since the purchase of my computer, and I did not buy Apple Care. So even if I were to take it in, I'm no longer covered under any warranty. The "blotches" have gotten worse, and while it doesn't affect the "usability" of my MBP, it's ugly and VERY noticeable. This whole situation has been very frustrating and somewhat unfair. I now have to pay 500 bucks to have my screen replaced on a machine I payed over $2300 for. Not cool.
