Yes, towards the extremes. Ball to ball within the same tier or similar would not make much of an difference.
I can feel the difference when I putt/chip. There may be a marginal difference with other clubs.
Will it affect my score? Almost certainly not.
The one ball variable which does make a difference is visibility. I reckon I find a yellow golf ball about once a round that I would struggle to see if it was white. That's 2 shots right there. More than most custom fittings deliver...
Strangely, the ball manufacturers don't seem to market the biggest equipment benefit available to a handicap golfer...
