(Well, there's a whole spectrum of this - the character is different depending on the temp.) I think most people prefer the character obtained from dry hopping in the mid to high 60s, whereas at the low 40s or even 30s you get a ton more "grassy" character and other less desirable things. I've spoken to many brewers who agree and I've proven it in my own brewery a few times. Now, with a beer that has already gone through a good dry hop period (5 - 10 days) most of the character is already extracted but you can still get some grassy & harsh notes if you leave it cold for too long after this. A couple days won't hurt you but just saying that if you leave it cold crashed for a week or more it'll change the flavor to something you might not like as much.
This would apply to hops in the keg too, yes? Not something I'd ever heard anyone talk about finding in that situation..
