'Extracting S (Saturation) channel of HSV color space with CLAHE applied to the V channel, does it matter?

I want to apply gaussian filter and CLAHE to an image but i have few things that's been bothering me. If I were to extract the saturation value of an image on HSV color space, should i:

  1. Apply gaussian filter on RGB color space before converting it into HSV?
  2. Apply CLAHE on channel V HSV color space? I reckon it won't affect the saturation value that i want to extract in the first place, right?
