I actually had that thought watching “all good things” when it first aired. Worf’s head wasn’t the same as it was in “farpoint” and Picard’s chair didn’t have the flip up panels (that was the most disappointing bit I love that chair - apparently it got stolen?). I just assumed that Klingon head ridges changed as Klingons aged or something.
Well, given Alexander’s development, Worf was probably younger Han Wesley in far point.
