If your GPU is Nvidia, no need to bother on DP 2.1 as Nvidia not support. Currently only AMD 7900XTX series support. 

 

Also only 57" Samsung Odyssey Neo G9 required DP 2.1

 

In summary,  DP 1.4 is far than enough.

Is the main difference between the DP cable 1.4 and 2.1 just more bandwidth? Is it worth the $30-$50 price hike? Thoughts?

Have you tried turning it off and on again? Maybe Restart it?

Yes.

Have any way to use that more bandwidth? higher resolution? Worth HDR? Higher refresh rate on your monitor?

Not English-speaking person, sorry, I'll make mistakes. If you're kind, maybe you'll be able to understand.

If you're really kind, you'll nicely point that out so I will learn more about write in good English.  🙂

To be clear, the main difference between those DP versions is bandwidth, yes, but not the cables. Displayport does not rate its cables in that manner (1.2, 1.4, etc..). The difference is in the DisplayPort spec. More to learn here: 

 

 

If you are hooking up a display with a specific resolution, refresh rate and bit depth that requires a certain amount of bandwidth, you my require a better cable. DP cables are rated by their bandwidth capability:

HBR3 cables are quite common today. 

 

What display are you trying to hook up?

So 1080p 75Hz? Nearly anything you buy will work.

Display usually come with its own cable that works for its maximum refresh rate and highest resolution, you shouldn't have to buy any monitor cable. TV is another story, but they shipped with HDMI, not DisplayPort
