Icon backgrounds tamagotchi 4u/4u+

[Mieru]

Hi everyone!
I was browsing through the internet and saw that there are several icon backgrounds for the 4u/4u+, I was able to change my 4u+ to the candy one but I was wondering if there are more or just the 5 that it comes with, and if so how do I unluck them?

Also is there any difference with the ones on the 4u? Because I saw a purple with jewels on a 4u and was wondering if I could get it.

Thanks in advance for your answers!

I don't think there are unlockable icon backgrounds on the 4U besides the built in ones sadly. 4U doesn't have much of unlocking content in general compared to previous color models...

Not sure about the difference though, as I don't have a 4U+.
