Dolby Vision metadata level 5 is used for defining shots that have different aspect ratios than the global L0 aspect ratio, avoiding L2/L8 trims affecting subtitles/blank space.
Use a DV metadata level 5 test video, and it seems infuse on macOS does not handle level 5 metadata, is it a bug or by design?

Was this sample video downloaded from YouTube?
If so, it may be a VP9 codec video and unfortunately these cannot be played in native Dolby Vision without hardware decoding. Hardware decoding of VP9 is supported by most newer Apple devices, but sadly it requires a special entitlement from Apple and as far as I know Google has been the only developer that has been successful in receiving this entitlement.
Was this sample video downloaded from YouTube?
No, the sample video is a test video made by the youtuber, and I downloaded it from google drive.

The screenshot of youtube video above is just the youtuber’s demonstration of correct behavior in his video, both top and bottom 280 lines of pixels will be masked, make the effective resolution 3840x1600, aspect ratio 2.4. I also tried the sample video on my TV(supports DV) internal player, RPU level 5 worked as expected.
Here is the link to the sample video.
