That is not ture, that cable link I posted above work fine with PS4 PS5 and PC on LG Ultrafine 5K.I have an LG Ultrafine 5K (connected to MBpro) and I can tell you that you can use any adapter configuration you want to physically connect it, but you will not get the display to turn on unless it's connected to a Mac, period. Nothing else will send the correct display signal. It was designed specifically to connect to the mac and they ensured this would be the case. Not to sound like a jerk on this, but it simply won't work as others have stated.
