Comment:

 Another test I provided on Windows with:
 PostgreSQL 12.5, compiled by Visual C++ build 1914, 64-bit
 POSTGIS="3.0.3 3.0.3" [EXTENSION] PGSQL="120" GEOS="3.8.1-CAPI-1.13.3"
 **PROJ="7.1.1"** LIBXML="2.9.9" LIBJSON="0.12" LIBPROTOBUF="1.2.1"
 WAGYU="0.4.3 (Internal)" (core procs from "3.0.1 3.0.1" need upgrade)

 The results are:
 -----------------------------------
 NAV4  POINT(4443865 5506116)
 WGS84 POINT(11.220567701891326 49.68910121081871)
 NAV4  POINT(4443865 5506116)
 -----------------------------------

 Thus these results are MUCH better but there is still a difference to
 Oracle and PostGIS Linux calculation of 0.47 meters.

 For our application this is quite ok. Still often enough it will result in
 a difference of a meter (calculating with this accuracy). But if you deal
 with real geodetic data this will not be enough. Keep in mind that Oracle
 and Linux PostgreSQL calculation only differs by 0.000118 meters!

 Axel
