You need to paint very large samples and see what happens on the wall. No need to do it directly on the wall.

Tell the contractor to hold his horses. You need the lighting in 4000k to see what the paint will look like.

if you can’t wait, I would go with the green undertone, and cross my fingers.

Don’t trouble yourself with undertones, check out their objective measurable attributes instead. (See link above)

They are both near neutrals from the Yellow Hue Family and can be prone to colour shift in certain imbalanced lighting.

Anew Gray sits closer to the Yellow-Red Hue Family and so can be inclined to shift purple in lighting which spikes more in blue/violet wavelength.

It doesn’t happen in every setting so as mentioned above, they require testing in your space to see how they render.

Analytical Gray may also shift purple but maybe less inclined to do so than Anew Gray as it sits just a touch further into the Yellow Hue Family. It is also more colourful than Anew Gray (more Chroma).

Analytical Gray may in some settings, show moments of greenness, a little like the sensation you might note when viewing a bronze.

Again you need to see how it behaves with your lighting.
