not that it wouldn't be a real one, bit early for copies already, it would just be one of the early samples, (the samples were intended for people to test, not to sell them, oh well) I have mentioned this multiple times but human nature being what it is, well some people just can't wait 😉
in the earlier firmware versions it does work much better with WDR turned off, there has been a lot of improvement since then though and the mass production spec will differ from what you have now but the firmware 'should' be ok for yours and still offer you a good improvement over what you have now, I say should because you'll have a different lens to what the mass production product will ship with and there will be some minor adjustments to suit the new lens
