I can't speak to the rest of the text or the laptops themselves, but as someone who works with color reproducibility in video and print, those photos comparing colors of two different screens are worse than useless.
Uncalibrated screens photographed at different angles in different lighting conditions are not a valid basis for comparison. If you want properly calibrated displays, you need to purchase hardware (datacolor makes one such device) and calibrate them.
Even "factory-calibrated" monitors will benefit from this, because the quality of that calibration varies widely and your color reproduction is going to vary based on ambient lighting conditions etc.
