I did recently see someone compare mpv and vlc on a 8k HDR @ 60fps file with mpv really lagging while vlc doing it fine. I could confirm the mpv lags but don't have vlc, so not sure if it's just better in that specific case or did something like no actual HDR
This may just be because mpv has higher-quality default settings for scaling and tonemapping. Try mpv with profile=fast, maybe. To properly compare mpv's and VLC's performance you'd need to fully match all settings across both players.
It was with the fast profile using both software and hardware deciding, important detail I forgot was that the video was av1. Don't have the link to it now but it was from jellyfin's test files
