Yeah, it does the same thing for me. But I would rather not see that blue background at all, not just after a minute

Seems this is not possible and the blue is there every time and turns black after couple of second. As you said the blue bg is there all the time when charging which I don't like as well. I can see dithering on the blue bg in low brightness so I would prefer it's black every time.
