Splash screen distortion for Samsung Galaxy S10

I have generated the splash screens for an app using the following site. See image of screens below.

However I am getting reports that a Samsung Galaxy S10 user is seeing a distorted splash screen.
The resolution for this device appears to be 2,280 x 1,080 which is quite long compared to the ratios of the images I have generated.

port-xhdpi is 720x1280
port-xxhdpi is 960x1600
port-xxxhdpi is 1280x1920

Any idea how to resolve this? Do I need to generate a different splash screen with a new image size?
