The sad part is, Nearly everyone could afford a $500-600 panel if they just "saved" a little longer...
It's worth Every penny.. 
There is nobody out there who could afford a $300 panel and would otherwise die if they spent $600 on a better panel...
How I'd LOVE to believe that a $300 panel is remotely close to a $600 one.

But let's not kid ourselves..
I'm not a monitor snob... But there's a reason they sell Scraped panels at HALF the price of "select" panels.
Lower contrast performance
Gamma curve Shifted too far from spec (un-natural odd color reproduction)
Brightness levels across panel surface uneven
Using cheaper Backlights
NOT tuned well at factories
Using cheaper Control hardware.. (makes a huge difference in sharpness, scaling artifacts, pixel responsiveness)
All the above, the average user will not know to check for..
I could understand paying a premium(15%-35%) to get the name brand upgrade, but in this case it's twice the price!

If you are saving twice as much you might as well buy two, then you can return one and keep the better to alleviate 90% of the quality issues you referenced
You better start believing it. You might be kidding yourself because you sound like someone who would wait in line hours on end to pay close to a grand for a phone because ‘paying more guarantees a better product’.
Yep there sure is but you forgot about the casing and stand costs where some of us use mounts and don’t need a $150 super swivel-tilt-pivot-hover stand, or just don’t want to pay for one and can get over the fact the stand will be low quality, but can be replaced later if they so choose.
In today’s day and age of enthusiast forums it is very easy to find guides and videos with all the settings needed to tweak your display and don’t need the company
assembling the hardware it to do it for you.
Sure, if you want something nice and shiny that works 99% straight out of the box without any user interaction what so ever, go pay whatever exorbitant amount of money will make you feel happy and justified in your purchase.
If instead you want a comparable experience at 50% of the cost, and aren’t afraid to get your programming fingers dirty tweaking your display settings, fixing backlight bleed by tweaking the screws and case (it’s SOO much easier than most people think to get rid of a majority of blb) pick one of these Korean badboys up. I would be willing to bet a majority of you would be very happy with your purchase.
The return policy on most of the Korean sellers is amazing as well, add on top of that SquareTrade if you so desire and if anything should go wrong, you are taken care of.
This is my opinion and only my opinion, people will spend their money how they so choose, I just wanted to share my experiences in this area.
