Definitely what I'm experiencing as well. I'm located in LA and actually took my OLED Bomb into the Red Store to compare it to theirs that they have on display. Same problem as mine (as as yours) - basically feels about 1000K too warm and about a stop brighter than the 5" LCD. I chatted a bit with the guys there and they agreed that the image definitely varied from the 5" LCD to the OLED Bombs and they felt that it will probably have to be something that gets fixed in a build upgrade.
Its a real shame though; when the camera first boots up that color chip chart that flashes looks breathtaking! And then actual the image really fails to impress but I think that the potential does exist. I hate saying this but the viewfinder on the Alexa (while not being perfect) definitely still destroys the OLED Bomb.
I imagine that this will become a much hotter topic of debate once RED releases the additional EVF/LCD module and everyone goes back to using viewfinders.
