different display for between mine and my wifes device

Hi all,

my wifes breathe display is completely different to mine in the app. 
My wife is using a Fenix 7S, i am on a Fenix 6X pro

This is how it look in both garmin connect apps. Left is mine, right the one on my wifes device:

   

Is this simply  a different way of displaying data? I do not have the "high/low frequency" also. 
Both are set to 1day / today. It is only different for "today". Switching to 7 days of four weeks equals the views for both.

My display did not change for years, but the display in my wifes app changed a few months ago.
Both devices are showing V5.12.1 as App version. Is this coming from an FW update on my wifes watch? 

Thanks
