Probably not noticable.

Probably not an issue

It never occurred to me to even think to measure something like that.

Apparently the cabinet has been not shimmed to compensate for the crooked wall. If that is the case, the top should be cut out of square in the rear to compensate for the crooked wall, keeping the overhang consistent.

A dimensioned drawing would be helpful.

Wow - thanks everyone for your comments. Makes me feel a lot more comfortable with this variation if that is what it ends up being.

Agree Joseph that more could be done to square things up (possibly including some more attention to the walls to begin with given new drywall was installed). We actually have two runs of counter showing the same issue - one on either side of the stove. But the bigger issue is thise two runs of cabinets are 1/4 inch out of alignment with each other (you can tell because the reveal on the front of the stove is different when put in place. Contactor is working to fix this up though so should work out.

And thanks to all for great advice on this forum. It has been really useful.

That would have been good info for your initial post a sit would have changed my answer completely.
