a320neo ToGa

The engine parameters don't show "thrust", they show rotation speed N1 and N2. Because the same engine can be rated for higher thrust 100% thrust for the A320neo is reached well below 100% N1 where as 100% for an A321neo with a derived engine variant would use higher N1 values for 100% TOGA thrust.

Quote from Chrisi

So this would mean „100% thrust“ on the 230neo are 87,6% as shown on the display?

The actual N1 needed to achieve 100% thrust changes based on outside air temperature, density altitude, bleed air selection and other factors such as engine age and so forth. So one day it can be 87.6%, the next day it might be 88.5% or perhaps less... the engine computer shows the target N1 for TOGA in the top right corner of the engine display. When the engine reaches that N1 value the thrust is pretty much at 100% thrust.
