Height screen qualifier is not taking the corresponding values

Question

I have a dimens file that has values that will be used for dp >= 615dp (h615dp)

I am testing the following device:

2055px of height  
screen density: xxhdpi
Dp = 2055/(480/160) = 685 dp

According to this answer: https://stackoverflow.com/a/43749616/20018861 , I have seen that the real screen height pixels are a little less that the pixels of the device, so I have used the following to see the real height's pixels of the device:

    DisplayMetrics displayMetrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
    int height = displayMetrics.heightPixels;
    Log.d("height", "height: " + height);

The real height's pixels are: 1911px

Now I am calculating the real dp:

1911px of height  
screen density: xxhdpi
Dp = 1911/(480/160) = 637 dp

Even having calculated the real value, we can see that it is still greater than 615dp

The problem is that even 637 > 615 , the values are not taken from the (h615dp) file and they are taken from the default file...
