Vanilla percentages

[Stacyspy]

Lately, I've been ordering FOs from WSP. I try to get mostly no vanillin, unless I plan on beige, tan or brown soap.
At what percentage does the discoloration start? If it has 1 or 2%, would TD be able to counteract the vanilla?
My new soapy plans should have a white base, and some of the scents I think I have to use have some vanilla in them.
I've read the reviews here and on the WSP site, but a lot of them don't have what I'm looking for?
Thanks for any input!

If it helps, one of my favorite FOs from them is their Sugared Spruce FO, which has a vanillin content of 1.5%. I am able to get a stark white color with it in my finished soap when I use 1 tsp. TD ppo. For what it's worth, my usage rate of the Sugared Spruce is .75 oz. ppo (very strong, long-lasting FO).

When I don't use TD, it turns a light tan color.
