There is a brightness setting for it. I haven't looked into changing the LED itself (if it can even be changed easily) but a cheap and easy "fix" would be to install yellow clear vinyl on top of it.
You can turn it off completely in the settings until you get the light color changed. I just used some cheap ($5 CAD) eBay yellow tint to change the color of my LED foglights for the winter. You could do the same for the overhead LED in the cabin.
Are you sure? I doesnt look like I can remove the light cover to replace the bulbs. They look like LED.Those interior lights are all DE3021 type bulbs. You can replace those bulbs with a warmer white LED, a colored version, or even an incandescent version like the one in the cargo area.
