Is gamma correction on a Mk2 device with firmware 204 needed? #260

I've looked through this repo, and there are a few different implementations of gamma correction available. I'm wondering which one is correct. I also would like to know which gamma correction value to use. Should I even use one at all?

The blink(1) hardware does not implement gamma correction, it leaves that up to the controlling software.

If you use the blink1-tool commandline program, the blink1-lib C library, or Blink1Control GUI app, those implement a gamma curve by default (and can be toggled on/off).
