Camera flash LEDs have traditionally been bluish-white, but frankly I think bluish-white LEDs suck as fill flashes. Most people prefer "warm" toned lighting, and a "cool" bluish flash filling in shadow detail in a room otherwise lit with yellowish-cast warm-white light is going to look weird -- and it's going to look weird in a way that's not easy to fix in Photoshop without masking and hand-tweaking. By making the LED itself more yellow, it might better match the normal ambient-lighting conditions where you'd normally use the camera.
Personally, I wish phones with LED flashes had a middle ground between "off" and "max brightness" for situations where you need more than ambient light, but full brightness is just going to make the picture's subject look albino.
