Anyone seen a disconnect between amenities listed in flight status vs. what is showing in the fleet site spreadsheet?

we are on SFO-LAX on Friday, flight status showing our aircraft is 739 # 3847, and amenities lists WiFi by Thales, and under entertainment simply says PDE. Fleet site seems to indicate this plane is NEXT. My impression is the fleet site has been always accurate for me, so kind of feel like that will be the case here, but not sure. Any thoughts? To be clear, either way, for such a short flight, it doesn’t really matter either way, but it matters more to my kids.

Ingerstingly enough, flew back from BUR last night on 319 N829UA, and flight status showed that same frame the entire time, but the amenities in the e-mail that got pushed to us also showed wifi/PDE only, despite it being NEXT, so there was a disconnect there also. I haven’t noticed UAs systems showing this kind of disconnect, except when aircraft are swapped, which to be fair does happen often enough last minute, but not the case here as far as I can tell.
