Yes, but does it really matter. We expect something strange at
startup anyway.

Well, for the devices we build at my place of work, random flashing at power-up like that would eventually put us out of business. Customers will not accept such glitches, period.

Everytime I plug in a header, the outlet flash. Is something wrong
with my heater or the outlet?

Well, the difference is that there you're switching a couple kilowatts at 100+ volts, i.e. it's quite unavoidable that there will be some sort of spark. That's a whole different story from a multi-MHz microcontroller apparently failing to keep a measly 100 mW LED from turning on for a hundred thousand CPU cycles' time.
