Runtime Efficiency of colorSpace conversion from BGR

I was profiling cvtColor (opencv 3.2) for runtime efficiency.
For an image of size 960x960, i got following results (in ms), for converting from BGR colorspace

On PC (corei5 2.4 Ghz)


On Raspi 3


Two things to know:
1) Why BGR2Luv conversion performace is so much different on PC and Raspi3 ?
2) Can we use LUT to improve the runtime Efficiency for colorSpace conversion ?
