RNP approaches. A question about the APV version and low temperature

Fellow aviators,


I try to come to a full understanding of the RNP APV (LNAV/VNAV) approaches and I am still lacking some understanding… Who can help me out here?

In ICAO doc 8168 II.1.4.1 it says:
1.4.1 Pilots are responsible for any necessary cold temperature corrections to all published minimum altitudes/heights. This includes:
a) the altitudes/heights for the initial and intermediate segment(s);
b) the DA/H; and
c) subsequent missed approach altitudes/heights.
Note.— The final approach path vertical path angle (VPA) is safeguarded against the effects of low temperature by the design of the procedure.

I am looking specifically at the correction for the DA.
The EASA AIR OPS AMC2 SPO.OP.116 2(i)(a) says for a RNP APCH LNAV/VNVAV:

when the temperature is within promulgated limits, the flight crew should not make compensation to the altitude at the FAF and DA/H; and

As I interpret this, there is a difference between ICAO and EASA. Anyone who can shine a light on this?
