LG UltraFine 5K Display dim each time I startup
Since you travel to and from home/work with your MBP fully powered off, I don't think resetting the SMC will make a difference. However, it may be worth resetting your NVRAM.

Resetting the NVRAM on Late-2016 MacBook Pro models

Your Mac uses Non-Volatile Random-Access Memory (NVRAM). To reset the NVRAM on all Late-2016 MacBook Pro models (with and without Touch Bar) follow these steps: 


Shut down your machine. Yes, a full shut down, not just logging out.
Press the power button and then immediately press the commandoptionPR keys. 
Keep these keys pressed down for at least 20 seconds!
Let go of the keys and let your Mac reboot normally.


Note: When you log back in you may need to readjust some of your system preferences (e.g. speaker volume, screen resolution, startup disk selection, time zone information, etc).
