The most energy efficient kind of light emitting semiconductor junction is the one that emits blue light.
This being a battery bank and assuming that 2x7 segment LED display is always ON, maybe the choice of color for it was driven by that (and price, since that numerical display is far cheaper than even lower power solutions like e-ink) above usability.
That doesn’t change the fact they are used in situations where they shouldn’t. I don’t like being blinded by a bright piercing blue light all the time.
Blue LEDs are great for when you need something blue in particular, but the color is piercing and way too bright. Then they are used as the default without any consideration for any other color.
They are shitty in how they are used, rather than their individual abilities and functions.
This photo is a perfect example of why blue LEDs are shitty.
Stop using bight-as-fuck blue LEDs piercing my retinas in the dumbest places.

Exactly, blue LEDs are cheaper. So, shove them in everything, even if another color or no light at all makes more sense.
Without blue LEDs we wouldn’t have LED lighting

Blue LEDs were a technological breakthrough that took decades of work to create and enabled pretty much all modern tech.
