A couple of the background images in dockscreens could be resized or altered to fit the new larger dockscreens. These are the ones I've noticed.

The first two, BattleArenaScreen.jpg and FirstContactMonumentScreen.jpg, only use a jpg image. They are placed at the top of the dockscreen display. There is a gap at the bottom.
The other 5 use an image and mask. These look to be centered vertically in the display.
MinedOre and RasiermesserFactoryHero look OK.
The last three look like the images have had bits cut off of them, either top, bottom or both. (Although not noticeable in this image, Pt Juno has a small slice of image removed at the top.)

Could also be some in CC and EP.
EDIT: Gunsan Complex has a background image which shows a gap at the bottom.
