I think the IFE gets GPS information only. When we fly on standard QNH it will seem a bit off that the IFE altitude is displaying something like 36143 feet. GPS altitude is actual altitude over mean sea level. Flight levels, on the other hand, vary in actual altitude depending on the current pressure.
