HDR format for HDR10+ content

MediaInof 23.04

New issue detected with HDR data format for HDR10+ content, because we no longer get what we need. The new Mediainfo no longer returns the information: 'HDR_Format_Compatibility': 'HDR10+ Profile B'

In this case, can you explain this difference to us? Is it possible to correct it, or is it an intentional change? If it is intentional, what is it based on?

Best regards

Tested on our files and it is still there:

Format                                   : HEVC
Format/Info                              : High Efficiency Video Coding
Format profile                           : Main 10@L5.1@High
HDR format                               : SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible

Please share a sample file demonstrating the issue.

Hello Here you can find sample, in the tow sample HDR_Format_Compatibility is not found, but not reproduce in mediainfo version21.09

And latest version of mediainfo HDR_issue.zip

In your file, the SMPTE ST 2094 App 4 profile is compatible with HDR10+ Profile B but colour primaries and transfer characteristics are not (they are both BT.709 instead of BT.2020 & PQ) + no mastering display color primaries, which are mandatory for HDR10+ so we decided to remove this tip because feedback from users was that it was misleading, they were thinking that the file is compatible with HDR10+.

Isn't a bug in your file that the color info is not the one for HDR10+?
