Bought a v4 Noctilux last month. Against a torch there is a light haze between the middle elements. Wide open in the evening I cannot see it in the pictures. Repair now, or leave it until it shows?

Noctilux f/1.0 v4 with light haze, repair or leave it?
Haze in a v4 is usually old balsam or grease vapour from the helicoid. If it does not show in pictures it will not get better on its own either; get a quote so you know what you are deciding.
Mine had the same and the clean cost about NT$12,000 in Taipei. Contrast against the light came back; wide open it looked the same.

This. And ask whether they re-grease the helicoid at the same time; it is the same opening of the lens.
