Photogrammetry question

While taking one of my saved flights from EGLC to EGLL (London City airport to Heathrow), flying over a lot of the POI's on the way (yes, I like to fly low and slow, lol), I noticed a new building on the right side of the Thames, just before the O2 building.

 

I do not remember that building being there in previous flights (could be mistaken??). Also, I have noticed that the POI's change from time to time, more are being added it seems. This is not occurring right after an update, For example, the BT Tower POI I just noticed a couple of days ago.

 

Does the photogrammetry get updated automatically, or is this occurring randomly? Not a complaint, just curious :)

It's possible that scenery objects can "pop-in" to view when you cross the boundary of their visibility radius as set by the developer. Some objects become visible from one angle sooner than another, which is a mystery to me - scenery building isn't my thing :p

That does makes sense, however, in this case, I always fly the same exact route (since Aug of 21). Scenery building is not thing either :) I am wondering if certain parts of major cities get updated to more recent versions?? Possible I guess
