Both are using band 20 its an iPhone 7 Plus, I am now using wAP LTE on current build 6.40.3 no difference and the LTE package is installed.
When I first set up the wAP LTE when I got it with the factory firmware the Status/Info on the lte1 interface was there, but after I upgraded to the latest version this option has vanished?
LTE package is not required.
What does it show on the Info/Status on the current version? You are checking that from Webfig/Winbox or console?
IPhone 7 Plus supports 3CA aggregation:

So it is possible that iPhone uses CA with other band as well.
Here is one link that might help to check if the phone uses CA or not (the the menu might be different as with the new IOS 11 that menu is also redesigned):
