Farrow & Ball - is it worth it for an almost white?

[NoseyNooNoo]

So, I'm sold on the F&B thing. I appreciate that the extra pigment is worth the extra money. However, we were going to have white but think we should have a hint of colour so we are going for 'Pointing' - but if it has so little colour is it worth going for F&B?

Also, this is the lounge - would it be wipeable?

And another thing - do they sell tester pots. I can't seem to find any on line.
