Probably, yes. At its brightest, you can see Venus during the day if you know where to look. In a dimmer sky, I'd expect Alpha Centauri A/B to be very obvious.
In terms of the sky, this is my guess at Earth (top) and Proxima B. It's hard to do a real comparison as of course your eyes would adjust in dimmer light, but it would seem dimmer and yellower.
