A location may skew wet, but our state is still experiencing a
drought that has been more-or-less present for the past 1 to 2 years, so the soil may be less consistently moist in that area than it would otherwise be. Still, yes, the shrubs with the better-looking berries may have stayed wetter overall. Insufficient root moisture might have caused any uneaten berries to shrivel, though eventually it's normal for any fruits that wildlife doesn't eat to shrivel as they dry out or start to decay, even in ideal circumstances. The shriveling doesn't necessarily indicate anything is wrong with the plant as long as the shrub leafs-out normally in April or May. (If it doesn't, it might have gotten too dry at some point so that branches died back.)
For any plant that appreciates moist soil, as well as for evergreens, it would help to
monitor them for watering needs as the plants get ready to put out new growth. The winter's prolonged freezes combined with a deficit of soil moisture was hard on lots of plants, even though the temperatures weren't unusually harsh. If any plants suffered branch dieback, they may regrow from the roots if the root system is otherwise in good shape.
