Vinegar has the option to force 1080p, via adaptive bitrate streaming, with the possible downside that the stream may start at lower quality, although I haven’t experienced that downside for some reason. Although perhaps that caveat only applies when using airplay. Either way, check the Vinegar settings from within Safari to find/set 1080p.
