Err - are you serious? There is no such thing as an HDMI 2.0 cable - the standard hasn't changed. Unless you had errors in your signal (visible as small dots or drop outs) with your old cable then your picture quality can't have changed unless you also changed resolution. HDMI is a digital signal, if there aren't errors, then a $1 cable will deliver identical pictures to a $99 cable or a $999 cable. There has been no requirement to change cables with the HDMI 2.0 standard.

I swear by it.. my eyes dont deceive me. I might have a bad cable I guess. But there is quite a bit of difference ...
If you are in the same viewing mode (i.e. same resolution and frame rate) and your TV is in the same viewing settings, and your previous cable didn't show errors (i.e. small flashing pixels or vertical lines dropping out) then there can't be any technical reason for this.
The same 1s and 0s travel down any HDMI cable. If they are correctly detected at the other end (i.e. you don't get flashing pixels or lines - which are both signs of errors) then there is no difference in the signal being carried. If your old cable wasn't delivering artefacts like flashing dots, lines of breakup, random large area blocks of colour (often green or magenta) or flashes to black, then it is unlikely it was doing anything worse than your old cable.
HDMI 2.0 in 4:2:2 or 4:4:4 50/60p UHD mode runs at higher clock rates than HDMI 1.4 in 1080/50p or an HDMI 2.0 signal carried 4:2:2 UHD 50/60p so it does put more demands on a cheaper cable - but if you don't see errors as mentioned above then your cable is working correctly.
Better cables don't deliver higher quality pictures via HDMI - that's the point of digital connections. It's why different hard drives and USB flash storage don't deliver different picture quality when storing the same file. As long as they can deliver the data rate required, you get an identical picture.
Whatever you are seeing is unlikely to be a result of your cable. It's basic physics.
Try getting someone else to keep changing the cables without telling you and watch the same content the same way every time. If you can then tell the difference - let us know what the difference was. If you think the picture looks sharper, colours look more saturated etc. be interesting to know how...
