Another SCP beta is rolling out now -- should hopefully resolve the issue with the new NR NSA band display missing on some devices. To clarify, this new field will only appear if the NR frequency is identified (i.e. the app is showing "5G-NR 2500"). If the frequency is not displayed, that means it is not available.. this information is not widely reported on NSA connections yet, although it is becoming more common.
@chamb your S22 was not reporting the information at the time of your report, that is why you are not seeing it.

I actually passed by this site last summer when I was searching for Staten Island keep sites and at the time it wasn't broadcasting the keep PLMN.
