There's a section of the Anandtech review on the display with qualitative observations and quantitative comparisons. They said it was the best display Apple had ever put into a retina laptop.
Yeah, I'm pretty impressed with this. In some of the categories, the rMB display actually came out behind the rMBP display but was ahead in most of them. Apple could easily put a lesser display into the new MacBook as it really is the consumer product, but they didn't.
Then there's the issue of quality control. When the Haswell rMBP came out, many people on these forums were returning/exchanging due to light bleed issues and all that. Something I never noticed, only a select few will. But it's worth a mention.
