If I open a new World, for ex. in Survival, and change the gamemode ingame to Creative, and leave then the game, then in the world selection there is the default gamemode.

Not a bug. This is because you are setting the local gamemode of the player, not the world.
If you want to modify the world gamemode, you'll have to modify the NBT tag for it, or use /defaultgamemode, but the latter doesn't modify the world difficulty tag.
Similarly, difficulty doesn't stay because the user has the right to reset the difficulty using the GUI settings. If you really want to force your players to play in a certain difficulty, hook up the command block to a redstone clock.
No, it is an issue. I just tried it, and with /defaultgamemode 1, there is a "Survival Mode" in the world selection..
Yes, I just said that using /defaultgamemode does not change the tag, but that is a separate issue. The one being discussed above is using the /gamemode command, which is different - look at his chat and you'll see that's the response for /gamemode, not /defaultgamemode. However, /defaultgamemode should change the tag, so that is a bug, but this is not.
Confirmed for 14w30c. Not only does it not change the tag, it doesn't work entirely. You can see this by running the command and then going into an NBT editor.
This also happens with the difficulty. If you have it set to hard in the options but then change it to peaceful with command blocks or whatever then it will revert to hard when reloading the world.
