No problem, I can appreciate wanting the highest quality version of a film, without any storage limitations.
I would say that given the source material used for these projects, you probably wouldn’t see any major differences with a larger data rate, and if anything that might start to cause playback issues when streaming the files from a NAS to a TV / Streaming Device. This is what happened when some other projects targeted a UHD-BD style data rate of 100Mbps.
