Top Padding in Carousel View on iOS

I have a CarouselView inside of an AbsoluteLayout. It is the only element within the AbsoluteLayout. This AbsoluteLayout is the only element of a ContentPage which has NavigationPage.HasNavigationBar="false"

When the CarouselView displays in portrait orientation on the device, it is moved slightly down, seems around 10 units to me. It's definitely the CarouselView as setting the background for the Absolute layout makes this background stick out in the gap. This does not occur in landscape orientation. Does anyone know how to fix this? I've tried everything.

Here is my XAML:
<?xml version="1.0" encoding="utf-8" ?>

<ContentPage.Content>

        <cv:CarouselView x:Name="IntroCarousel"
                     ItemsSource="{Binding Path=BindingContext.Intros, Source={x:Reference IntroPage}}"
                     PositionSelected="pageChanged"
                     AbsoluteLayout.LayoutBounds="0, 0, 1, 1"
                     AbsoluteLayout.LayoutFlags="All">

            <cv:CarouselView.ItemTemplate>
                <DataTemplate>
                    <StackLayout BackgroundColor="{Binding backgroundColor}"
                                HorizontalOptions="FillAndExpand"
                                VerticalOptions="FillAndExpand"
                              Orientation="Vertical"
                             Margin="0"
                             >

                        <Image Source="{Binding ImageUri}"
                           WidthRequest="250"
                             HeightRequest="150"
                             HorizontalOptions="Center"
                             VerticalOptions="Center">
                            <Image.Margin>
                                <OnPlatform x:TypeArguments="Thickness"
                                 Android="10, 10, 10, 10"
                                 iOS="10, 30, 10, 10"
                                 WinPhone="10, 10, 10, 10" />
                            </Image.Margin>
                        </Image>

                        <Label Text="{Binding Heading}"
                           FontSize="Large"
                           FontAttributes="Bold"
                           TextColor="White"
                           HorizontalOptions="Center"
                           VerticalOptions="Center"/>

                        <Label Text="{Binding Description}"
                           TextColor="White"
                           HorizontalOptions="Center"
                           VerticalOptions="Center"
                           Margin="10, 10, 10, 10"/>
                    </StackLayout>
                </DataTemplate>

            </cv:CarouselView.ItemTemplate>
        </cv:CarouselView>
    </AbsoluteLayout>
