Battery voltage display

So now that I have had my 2023 super duty for some time I notice the battery voltage display appears to be more of a dumb display. It only shows 14.0 or 13.0 so far. So I guess charging and floating.
anyone else notice this?

I have seen 14.5 at times on mine, but I don't watch it a lot.

My 2021 with dual alternators runs around 14.5 most of the time, As high as 14.7 on occasion or as low as 13.6.

I obtain my readout on the banks idash.

Using Forcan Lite I can monitor the battery voltage and current. The voltage varies from 14.5 down to the low 13's. The current starts out high but after driving a long way it gets down to 0. I'm guessing a bit on the voltage readings but I know they change on ForScan by tenths - I just don't watch it closely tho.

When I started my truck this morning I watched it go from 12.0V to 14.5V in .5V intervals, so it is not a dumb display, it just has a .5V granularity.
