Hello helloimprin,
Congratulations on your new MacBook Pro! I would be concerned too if I was noticing some pixel anomalies on my new computer. I found an article that has information about pixel anomalies and what to do if your LCD panel has pixel anomalies:
Many Apple products use liquid crystal displays (LCD), including the iMac, MacBook, MacBook Pro, Apple LED Cinema Display, iPad, iPhone, iPod touch, iPod classic, and iPod nano. LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a corresponding transistor responsible for turning that subpixel on and off.
Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD panel used in the iMac (27-inch, Mid 2010) has a display resolution of 2560 x 1440, which means there are 3.7 million pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 11 million individual picture elements on the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off (dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.
In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store.
If you are concerned about pixel anomalies on your display, take your Apple product to an Apple Authorized Service Provider or Apple Retail Store for closer examination. There may be a charge for the evaluation.
