DP 1.4 and DP 1.4a are basically the same.

This does not mean (and never did) that a particular Thunderbolt 4 port will offer these display capabilities. They are simply pointing out that the transport capability of Thunderbolt 4 is sufficient to support these (example) display configurations. No, there isn't any lie (why to people make idiotic statements like this?) it is simply you misinterpreting what you are reading. For the rest of it, you have again read too much into it. Your final statement is correct (as is your bandwidth statement).
