Yep, often it makes more sense to use hand or robot soldering in production. For example when TH soldered on top side of PCB as in this case, or some other case where wave soldering is difficult to do or not justifiable from economic standpoint. For example if you just need a few contacts soldered, hand soldering is faster and cheaper.

Why it's not OK? There is nothing wrong with this. As of flux, if it's not some low leakage circuit where flux may cover unwanted gaps between the traces, other than cosmetics there is no reason to clean it. Also cleaning it is no so straightforward as it may seem. Simply cleaning it with IPA will spread the flux all around and probably under SMT components where tiny leakage current actually matters. And getting rid of so there are no visible signs of its presence will take order of magnitude more time than soldering that connection.

It's a high-end meter, not a home-made blinky; I'd expect better.

You'd be surprised. But as devices become more expensive and produced in lower numbers, the amount of bodges goes up. In this case it's not even a bodge.

AVGresponding:
Yes, I understand; it's more practical to create a mod-board than to re-spin the main one, usually.

Keysight is not known for making perfectly clean PCB's.
This are the PCB from DSOX2002 - flux on the bottom of the board. Maybe they keep the boards as the laundry dries on the wire :)
