Not sure about now but I think Dolby Vision didn’t work very well with IINA the last time I tried it. For me, Infuse just works with anything I throw at it and has Jellyfin support which altogether makes $15/year well worth it for me
Its got a sleek and easy to use UI, is jam packed with features like customisable gestures, no ads, a great media player and (I think) lots of accessibility features.
It’s also wonderful that the dev loved his app and continually updated it
