5D III AF Point brightness (light red)

Folks I am not sure if this is addressed or not. I am experiencing the focus points to be very dim when the focus is locked. Yeah I am talking about single shot not servo

5D II points are much brigher red.....this one when focus locks in very dark room you see it is red else I see black points.

It is turn on, setting is correct

Should I send it back and ask for swap
