1. Teleporting from the Nether to the End using an end portal (only possible in creative mode) will show the same loading screen as if you went through a nether portal. Which doesn't make sense since you just went through an end portal and you can only get to the End through an end portal anyway.

2. Jumping into an end portal after having set your spawnpoint in the Nether using a respawn anchor will use the nether portal loading screen instead of the end portal one (which is should since you just went through an end portal)

Just in case the reviewer considers case #2 to be a WAI because "the loading screen matches the dimension you're traveling to" that's clearly not true because then there'd be a custom loading screen for traveling to the overworld which there isn't. And either way case #1 would still be inconsistent.
