Image does not appear completely white even though it is correctly white

For a splash screen, I use an image that contains a white background (pure white - checked in Photoshop). For some reason, it shows a small green bg compared to the default active white bg - as noted in the screenshot. Only on some devices, such as

ImageView graphic shows now white background despite the image uses white

I add this as a separate view in the frame layout to the activity:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:scaleType="fitCenter"
    android:src="@drawable/splashscreen" />

</FrameLayout>

Any idea? I read about problems with RGB888 and RGB565, but could not find the right solution.

Note. I am sure that you can make the white change in the image transparent, but they prefer to understand the problem and find the right solution.

You can also define the background for your FrameLayout or your ImageView using the color of your image (which seems F8FCF8):

Android: background = "# F8FCF8"
