Companies that aren’t profitable get bought all the time for ridiculous amounts of money not because they currently make boatloads of money, but because they have a huge userbase and brand recognition, and the buyer thinks they are the geniuses that can make it do that. Yahoo paid 1.1 billion for Tumblr - since sold to wordpress for 3 million - and Musk 44 billion for Twitter - now worth a fraction of that - for example.
That is exactly why they often go to shit only after they have been bought.
Fwiw, Honey did around $100 million in revenue back in 2018. That’s 40 times less than what they were bought for, and that isn’t even profit, but just how much money they received before all their business expenses were paid.
Actual film doesn’t work like that (35mm or 70mm IMAX for example), but you are correct that most cinemas these days are digital and they use “1080p” (more accurately DCI 2K which is 2048×1080 when the aspect ratio is 1.90:1). There are a few that do 4K, but overall not that many.
The main reason that’s enough for cinema though is that those “1080p” films are like 500GB with very little compression displayed through a DLP projector, so they look a heck of a lot better than showing a blu-ray through a massive TV with palm sized pixels.
