It's quite common for factory fitted LED's to be either yellow or "white" (often the white are too bluish or cold looking).
For example I have 2 Roco SNCB 20's - the early one has bulbs & the later one has yellow LED's. The early one looks better. I will change the yellow LED's when I have the time.
There are quite a few suppliers of "golden white" LED's including DCCConcepts - these look far, far more realistic. They don't cost that much more so I don't know why they are not fitted as standard.
BTW - I have used yellow LED's for tailamps behind red lens - dulls the colour down quite well.
