You'll need to know the spectrum holdings and compare the channel details (centre frequency and bandwidth) to see which one is wrong.

In here for fond answer. You said one of these reporting wrong. In in czech republic. And what Is thé modem, that reports wrong values? Mediatek or Qualcomm? 100kHz different Is with all operators (O2, T-Mobile, Vodafone) And all NR bands (N3, N1, N78, N28). 

There Is screens fór Vodafone N78

With 5G there's two NRARFCNs. One is for the centre of the channel, other is for SSB location (equivalent to GSCN, and can be converted to GSCN).

Are you sure you're comparing the same NRARFCN on both phones?

Edit: just checked your screenshots and the channel NRARFCN is indeed slightly different as reported by both modems. There's a delta of 100 kHz. This is strange as it's the same cell and gNB. Maybe one of these modems is reporting it wrong . Btw, you're in Czech Republic? Why are you asking in PM forum?

Why do you use this app? What are you trying to accomplish with it?

And do you understand what the acronyms mean? What the technologies are, what you're trying to compare?
