Skyrim VR

Hello,

i'm on 5.05 HEN and i want to update the latest patch for SKYRIM VR (graphical update) with 1.4.40.0.8

it's the last update, i found the pkg it on a website : EP1003-CUSA08933_00-SKYRIMVR00000000-A0104-V0100.pkg

But i see : System Version: 5.55

you think it's not a good idea to install the game update ? (i've the official game BR for info)

You know how to have the 1.4 update on HEN PS4 ? or it's impossible before to have a 5.55 kexploit ?

Thanks by advance
