According to the specs on Kona's web site, current Dew models
are spaced at 135 mm, just as you suspect.
Like Bill mentioned above, it's possible that the shop added a longer axle and spacers to the Claris hub to effectively respace it to 135 mm to match the frame.

If you've got a 130 mm hub installed in a 135 mm frame, the frame would be flexing more than its designers intended when clamped down on the smaller hub. The stays would be flexing along their length, plus the frame would tend to flex at the dropouts because the clamp force of the QR against the axle's locknut would attempt to pull them into parallel. In a worst-case scenario, the flexing could eventually lead to cracks in the bike's frame -- especially since it's aluminum and the aluminum alloys used for bikes don't generally like to be repeatedly flexed like that.
If the new wheel is 130 mm and the frame's 135, definitely contact the shop. I'd see if they're willing to do an axle swap and add spacers to respace the wheel since that would be a quick & simple fix.
