Lots of interesting comments above. I can easily accept that a significant change in velocity might affect patterns some but seriously doubt that different pressures would make much, if any difference. I also very much agree with Rocket's question as to what is usually meant by "beautiful", "perfect" or "greatly improved" patterns.
My strong suspicion is that it usually means about the same as when some obvious newbie(or even many oldies) mount a new shotgun in a store and eloquently proclaim it to be "nice and light" or "has excellent balance". Most of the time it is the same material as the pile found under a peddler's wagon horse's tail, after he's been parked too long and just about as useful.
The clerk, who likely knows even less about the subject will say, "absolutely".
