Your new MacBook Pro probably has a much higher resolution Retina display. Unless you're looking at an original high-resolution version of the image on your new laptop, a preview or scaled image will look much worse. I'll bet your new laptop has like 4 times the resolution of the old one, but because the screen sizes are similar and the OS has high-res images for its UI, you think the screens are basically the same.
