I have read that the Normal mode uses the sRGB colour gamut and the Vivid mode uses the P3 gamut.
Anyone know if this is correct and which is best to use when editing photos ?

Well it looks like nobody in the this community knows the answer to this one.
So for those that are interested I have been and asked in the Jessops camera store in Nottingham.
They said when you're editing photos go for the Normal colour mode which is sRGB. Most screens still use sRGB and there printers also use it.
