Yes - only use rec709 if your monitor can do rec709. color

I feel justifiably ready to comment on this after ( A SHIT LOAD) of theory 
research on my own project.

The alpha thing makes sense to me - as alpha isnt for 'viewing' as such - its a 
data channel for comping - setting to linear will darken the perceived image 
meaning you can perhaps see more detail.
