Well in Spain it doubled the opening week of Uncharted 3 (again without digital sales even). That is already two biggish markets with very clear increase compared to Uncharted 3. Hard to see that the situation would be that much different elsewhere.
In Japan first week was just ~4k better (plus digital) with one day more for Uncharted 4.
Too bad we don't have sell through for U3, we can just speculate how much of 3.8 million was sold in one week.
