I nerded out pretty hard over LED color when I did my red truck, it does make a big difference. IIRC it was a pain to find warm white rigid loop festoons for the map lights that matched the replacement I had in the dome.
I liked what I ended up with, but some of them would always do this weird flicker whenever battery voltage fluctuated even slightly. I remember the map lights would do it just sitting idling sometimes. Swapped back to incandescent and all those issues went away.
