OK,
so after a little more research, I think I found the problem. As far as I can tell it's completely unrelated to Hybrid, so sorry for posting about it.
Seems like these .sup files contain PGS subs that are bitmap based and essentially, the subtitles look correct in HDR but too dark in SDR because the tone mapping that normally brightens them is absent or handled differently.
Anyway. That's that
All the best.
