If it's not showing tiles, it's because you're trying to watch something like VP8/VP9 where the alpha component is a demuxer hack and not part of the video stream. This would be an ffmpeg issue.

i checked file mpv.conf alpha=yes not work tiles alpha=blend-tiles not works tiles alpha=blend not works tiles

what i will do..? ( i wish mpv make it tiles (checker) for DNxHR (include alpha)

What you should be doing is ask ffmpeg to fix alpha for your format
