That is an overly general statement and can also be used against 1920x1080 resolution screens as well. Generally speaking to get a 1920x1080 in a relatively inexpensive laptop also means the 1920x1080 needs to be inexpensive. Higher resolution does not automatically mean better contrast.
The only 15.6" 1920x1080 display that I have ever known to be of poor quality was the AUO B156HW01 V.5 that was used in some of the older ASUS G-Series and N-Series computers before ASUS switched to matte 1920x1080 displays for these lines, and the only 15.6" 1366x768 display I have ever seen that had decent contrast was in a Lenovo laptop that I had in other cases seen including a very poor display of the same 1366x768 resolution.
These are two isolated cases. Every other 15.6" 1920x1080 display I have seen in person or have seen calibration data for had well-above average contrast, and every other 15.6" 1366x768 display I have seen in person or seen calibration data for had very poor contrast. Only in rare cases are you going to find a 15.6" 1920x1080 display that is poor in quality due to contrast, or are you going to find a 15.6" 1366x768 display that has considerably higher than average quality due to contrast.
Specific to the computers I recommended, I have personally seen multiple HP DV6-6000 series computers that have the 1920x1080 display. The displays in these computers were indeed much better in quality than 15.6" 1366x768 displays tend to be.
I do not know exactly why 15.6" 1920x1080 displays tend to be well above 15.6" 1366x768 displays in the majority of cases, I only know that they do based on experience, and make guesses about manufacturing processes that might explain why. You are making the assumption that there is no correlation between contrast and which resolution a 15.6" display has, and then you try to backup your assumption with a guess about manufacturing processes that you don't know is a significant factor or not. The difference is that I have a large amount of experience and that I have done a considerable amount of research on the issue.
I already explained this in further detail the last time (including calibration results from numerous displays) and I do not want to do it again unless I need to for the sake of the OP's proper understandment of the issue.

But image quality aside, the resolution itself is an issue that will in most cases outweigh the differences between most available processors. The average user would be affected much more by being able to fit more onscreen at a time than he would be by upgrading from a processor that already has more than enough performance not to be a bottleneck for any tasks he will perform, to an even higher grade processor.

Another way to think about it is: Essentially any CPU and dedicated GPU you select in a new laptop will be a quantum leap over what was available in most previous systems. But if you aren't careful to make sure that you get a decent display then you will most likely have a similar or worse display than what was available in many previous systems.
