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.

The brightness is too bright, not the color. The brightness is always a choice by the manufacturer they could easily make it dimmer using the exact same components.

You literally can’t make white LEDs without them. That includes all flat-screen display technology. After the development of blue and green LEDs, decades and untold money were spent trying to develop blue LEDs.
The device you’re reading this message on is only possible because of Blue LEDs.
Your issue isn’t with the blue LEDs - it’s with the atmosphere, which absorbs red and green light more quickly than blue. It’s why the sky appears blue. it’s also why white LEDs bulbs will often have a yellow filter on them to absorb some of the blue light. Because pure white appears blue-ish in hue.
