Fetching to WorldElevation3D/Terrain3D is returning wrong altitude

[LuisSolaRuiz]

Hello! I am working to obtain the altitude of certain points but I receive different information depending on the source I consult.

When I query the information of a point through the identify property of the WorldElevation3D/Terrain3D layer, it returns an altitude of 433.707m.

Instead, if I query directly to the elevation Layer of my project that is equal to this one, I receive a z-value of 569.0930288257836m. This altitude is the right one. 

Layer Definition: 

ground: new Ground(
    {
        layers: [new ElevationLayer({
            url: '//elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer',
            id: 'groundLayer',
        })],
    },
),

Query the layer: 

map.ground.queryElevation(point)

Why is this behaviour happening? Thanks
