I do think this is an interesting topic, more along how a film is distributed and how they decide the number of screens, etc. Would love to hear from someone that actually knows. I'm guessing there is nothing sinister going on in your example, but here is how I understand it:
Angel Studios acquires the distribution rights from Disney, then crowdfunds $5MM for Print & Advertising to make actual digital copies of the film and market it. There is a finite number of copies they make with that money, which then equates to the number of screens they can negotiate with theaters.
What I don't know is the terms of their theater agreements. Sometimes it's "you buy this print for x, and we'll include this marketing, and you recoup your expenses through ticket sales", but I believe it is becoming more prevalent to share those costs between theater companies and the distribution agent and you each get a % of ticket sales to recoup your investment. Number of prints/screens and weeks of guaranteed showtime are all part of the negotiation. Obviously, larger blockbuster movies/studios will command a higher price, higher number of prints and guaranteed number of screens.
So, in your example, Star Cinema may only have a limited number of prints (really a hard drive with digital file) they can use at any time, unless they go back to Angel Studios and request more. They also have to contend with contracts and guarantees they've allocated for the other films. If they have more money expended into Indiana Jones or M:I, then showing them in half-empty theaters may be a smarter business decision than trying to negotiate for more showings of SoF, because they need to make their money back and have guaranteed terms with the Distributors of those other films.
All this to say, I don't think it's as easy as the Manager saying "take these showings down and add more of this one" without alot of behind the scenes action, that would include negotiations with Star Cinema (not local theater, but the Company) and Angel Studios.
Maybe I'm wrong, but just my input.
