How to stream 4K versions of downloaded movies from TV app on Mac?

I've downloaded purchased movies from the TV app on my MacBook because I don't have wifi or cellular service where I live. However when I am able to connect on wifi I'd like to stream the 4k versions (if available) but the app only plays the downloaded 1080p version. Is there a way to stream the 4k version if I've already downloaded the 1080p version? A quick search suggests deleting the movie from my library then streaming it but that isn't ideal as I'd have to redownload it to watch offline in the future. Any suggestions much appreciated.
