You really shouldn't see LCD refresh flicker... but you MIGHT be seeing the back light flicker. Newer MBPs are all LED tho, right? Have you fiddled with the brightness to see if the flicker changes speed? 
Yeah, my main issue with all the korean monitors is the lack of 16:10.
The apple cinema Display that features the same panel has a nice glass front, some USB ports, and even has a fan inside it.
Yuck
Regarding the flickering: The only way that I know for that to happen is because of the backlight flickering. It happens when the backlight is set too low and there is bad PWM control on it. Especially "green" features which, in order to save energy, turns down the backlight waaaay down instead of making the LCD crystals block more light in order to achieve deeper blacks. I would suggest you turn of any energy saving features and similar and see if it helps.
Given how easy it is to do PWM at higher frequencies (with a shorter pulse width/ duty cycle) I'm surprised they'd end up with a value so low. I had thought it had something to do with the panel, but backlighting makes a lot of sense. The MBP displays (glossy, from 2010 or so -onwards) might not have been at their birghtest setting. I'll look at it next time I get to work on one.
I guess I sort-of assumed backlighting wouldn't be an issue. My guess was the panel was doing something weird, like quickly (but not fast enough!) rotating the pixels between two states (Dithering?) that I could see.
That said, I am still very much considering one of these, so if anyone has had issues with the backlight flickering please Pm me or post about it here.
