For some reason, the phone seems to be trying to get the download from the Galaxy Store, which is an odd place to get a system update.
Ah yes, this is new. Samsung has done a lot of work splitting out there updates from google android updates. A lot of samsungs "add in's" can now be push via there galaxy store (i.e. always on display). This can be done now because of project treble in android 8 and 9
