Exclamation i9505 New 4.4.2 update question

Hi guys, i have a Galaxy S4 bought a month ago, right now it have 4.3 jelly bean installed (I9505VJUEMKE) it is carrier branded (Entel Chile), well, today in Sammobile they published an Open Europe 4.4.2 Kitkat update listed here:

Model: GT-I9505
Country: Open Europe
Version: Android 4.4.2
Changelist: 481100

My question is... can i install this firmware on my GS4?
