DisplayPort cables are not classified by "version". Although cables are commonly labeled with version numbers, with HBR2 cables advertised as "DisplayPort1.2 cables" for example, this notation is not permitted by VESA. The use of version numbers with cables can seem to imply that a DisplayPort1.4 display requires a "DisplayPort1.4 cable", or that features introduced in DP1.4 such as HDR or DSC will not function with older "DP1.2 cables", when in reality neither of these are true. DisplayPort cables are classified only by their bandwidth certification level (RBR, HBR, HBR2, HBR3), if they have been certified at all.
