No, that $434M was already half of the total expected box office. Going off this Forbes estimate:

Also, yes, they probably know they are losing DVD sales but that still doesn’t mean they aren’t losing that. There’s still the movie sales that Disney would like to capture before making the movie available on D+. If you think they’d just give that revenue up, you’re crazy. Before digital, movie sales would often be more than total box office, especially Disney movies. Would they still make the movie available to buy via Apple, Prime, Roku and whatever else there is? I’d think so because there has to be a big enough gap so that people who don’t love the movie theater just say I’ll wait until D+ because it’s only a few months away.
Maybe there’s a tiered price. First 3 months, it’s $29, then there’s a two month wait, then $19 for 6 months (could include Apple and others) and then after two more months it’s on D+.
I don’t think movie theaters will go away but I wonder if Netflix might start offering a VOD option for studios that don’t have their own service. Almost like a movie theater splitting box office where Netflix can get them a huge audience that might be OK spending $3 on a new movie that isn’t Black Widow. @Netflix, please send me a few shares for the idea, TIA.
