Looking at car behaviour it seems obvious ferrari is loaded with quite a lot more fuel than perez is.
Apex speed at T6-7 is 10 km/h lower than in 2022 Q3 even on a lot faster tyres (c4 + faster tyres in general), but it's 10 kmh higher in T4. This tells me sainz isn't pushing a whole lot.
There's absolute boatloads of time still left in that ferrari.
