    Same issue here -- 2019 seems to remove ReadPixels support for a lot of formats that are relevant to my use case. As of 2019.2.15f1, on DirectX11, the following code snippet:

    [ Test ]
    public void ReadbackSupport()
    {
    var read_formats = System.Enum.GetValues( typeof( GraphicsFormat ) ).Cast<GraphicsFormat>()
    .Where( f => SystemInfo.IsFormatSupported( f, FormatUsage.ReadPixels ) )
    .ToArray();
    Debug.Log( string.Join( "\n", read_formats ) );
    }

    returns only the following formats:
    R8G8B8A8_SRGB
    R8G8_UNorm
    R8G8B8A8_UNorm
    R16_UNorm
    R16_SFloat
    R16G16B16A16_SFloat
    R32G32B32A32_SFloat
