iOS rendering issue

Hello,

We have a big problem with render on iOS with UE4.24
We don’t understand why the entire rendering looks very low definition.
The first screen is a Metal 3.1 preview on PC and the second screen is the actual in-game rendering on IOS 13.5.1 (iPhone 11 Pro)

Have you got an idea of why it’s sooo different please ?

Thank you and have a good day
