For North America:
FM and HD radio logos are entirely up to the stations broadcasting.
SiriusXM logos are contained in the Sync software, but Sirius also updates logos OTA.
DAB is mostly EU only. There is no DAB in the US, at least in this context.
Calm screen can be enabled with FORScan. It is not an option available thru the Sync menus. Being you have a 2018 Explorer, your APIM might need a firmware update to enable it anyways.
Hope this helps…
