Sony does not AF wide open with bigger apertures? And behaves differently with different lenses in this area too.
For a constant live view feed you have to deal with a limited exposure time range you can use for the live view video feed, and with the slow-ish read out of the sensor too. Also, beyond that exposure time limit, often cameras "simulate" the exposure in live view so that within the exposure range the camera can use during live view the user does not get an overexposed or underexposed image which would not at all show the actual exposure outcome of a image capture. Canon calls this "Exp.Sim" or "Exposure Simulation", which itself has a little bit limited range too (so if you use very odd settings you still can get a too dark or too light live view feed).
Too early here (GMT +!) to theorise more on what Olympus actually does and why.
