I was able to do some research and that is correct. The manufacturer makes minimal upgrades and changes depending on the hardware version. As the EAN codes and manufacturer numbers are the same, unfortunately we cannot guarantee which version will be supplied. As long as there are some of the previous versions in circulation, there is a chance that you will receive one.
I'm answering my own question. October 2025, I ordered and received an X50 V1 deco. But it seems that V1, V2 or V3 is not a question of evolution. It's just a hardware version. According to TP-Link, V1 is the version that receives Firmware Update first.
