It was a change from the trailer, not the finished film.
Yep. Fortunately many redditors have pointed this out and the OP has said “oops, shouldn’t have posted this” after ranting about it in a number of posts first. Now we’ll get to see it pop back up every few months in an “OMG you Lucas h8ers are hippocrites!!!”.
Still, I’m intrigued as to why they were changed.
In one of the interviews on the making of the film, someone (JJ?) described this as one of the most time consuming effects shots in the film. It’s quite possible that they worked on tweaking it more after the trailer. Whether the previous flags were placeholder easter eggs, or there was a new decision, whether due to PT content or aesthetic is a mystery for now.
I think the same interview described the final shot of the Falcon landed on Luke Island as another surprisingly tricky shot, due to how many sources they needed to combine. Kinda reminded me of the various sources that make up the Falcon docked in the Death Star hangar in SW.
