HDR to SDR feedback - situation with poor tone mapping of content

Server Version#: 1.21.1.3830 on docker synology and same on an 8th gen i5.

First off kudos on the HDR to SDR tone mapping. i’m posting this for feedback/identifying issues rather than criticism - seems to be working great 90%+ of the time.

Watching a movie today and the HDR to SDR tone mapping was waaay off in very bright (explosion) highlighted areas. Blown to purple - very noticeable as all the explosions instantly take on a cartoony effect and look ridiculous.

Same movie direct played looks great, and on SDR copy with no HDR looks great - it’s just a failure of the tone mapping to cope with this exceptionally bright/coloured area I think.

IMGUR album here: https://imgur.com/a/1rj3kkg shows a direct set of comparisons where the explosion is clearly blown and purple rather than tone mapped at all decently.

That’s an interesting example. That movie is known to have VERY bright hilights.

Yes I think it’s possible it’s just the extremity of that example that might have pushed the tone mapping into clipping a bit too far. Rest of the movie/scene looks fine

Just flagging as an example in case it helps further development etc.
