Ok.... look. I am working on a PhD in Robotics and hold an MS in electrical engineering. These spots will go away, but only after many on/off + rgb + bl cycles UNLESS the screen is cracked. Electrons displace themselves from each other. At some point, something got squished. My advice, use your device SPARINGLY but DO USE IT. Turn on the display at least once a day, no more than a dozen, for a few weeks. If the spots are growing, you may have a seal problem preventing the screen aligning itself. If they are EXACTLY the same. New screen bezel, sorry.
Finally, NEVER .... never never EVER let the device completely discharge. Connecting power after that is kind of kicking the problem in the teeth.
