I think its pretty safe to say you would see little to no detrimental effects long term.
In fact something boosted into the high 14s or low 15s may actually help the overall electrical system especially with higher electrical loads.
With higher voltages you generally reduce the amp draw for the same wattage load and helps fight again voltage drop at the load end... most appliances light fridges, car amps, and most other things are happier being in the higher end of supply voltages anyways since the efficiency figures go up.
For example if you look at the RMS / Peak ratings on a car audio amp that makes 300 watts, that wattage rating is at the maximum input voltage of the device.
For the sake of the example lets say that's 15 volts...
15 volts x 20 amps = 300 watts
The amp wont exceed 20 amps, as protected by a 20 amp fuse. Lets assume the voltage is 13.5 volts now...
13.5 volts x 20 amps = 270 watts.
The maximum power output of that 300 watt amp is reduced due to 270 watts in a 13.5 volt system.
Most everything is more efficient on the top end of of its input voltage... Ham radios, winches, you name it. Less amps, less heat, with more voltage.
