Creality K2 Plus: How to Identify the revised Extruder, with only your EYES

Any1 know if this fixs the coupler going bad on older design?
Will creality replace with new design if you hadn’t had issues yet?

[Chris.S_NZ]

Any idea if the revised extruder has a more easily replaceable PTFE connector ? or one that is less prone to breaking ?
On the Ender 3v3 variant of the extruder the connector its held in via a screw, so easily replaced, not so on the Original K2 version.
