A DisplayPort cable is a DisplayPort cable. They're all the same as long as they follow the specifications that are part of the standard.

Despite what you may read, there is no such thing as a DisplayPort 1.1 cable and DisplayPort 1.2 cable.  A standard DisplayPort cable, including the so-call DisplayPort 1.1 cables, will work for any DisplayPort configuration including the new capabilities enabled by DisplayPort 1.2, including 4K and multi-stream capabilities.

It's a digital signal, so cable "quality" is pointless. It either works or it doesn't. A $10 cable is fine so long as it has all the right connections (it will). Displayport 1.1, 1.2, etc are all information transmitting/receiving standards using the same cable. There is no different cable for each. Same reason an HDMI cable is an HDMI cable. No such thing as an HDMI 2.0 cable.

Irrespective of what the above are saying, and what they're saying being true, I've seen really cheap DP cables create flicker on supposedly flicker-free displays. So in a way you may get what you pay for, up to a common sense point of course (there's no $1000 cable that will improve anything above a run of the mill cable)

Then I would argue that they're not following the DP specification because flickering should not occur.

That is also true, though there are plenty of factories in China that think "specification" is the German word for a Coke.
