Hi,
when reading out the channel info for a Multi Part OpenEXR file, only the channel names for the first Frame inside the OpenExr is read out.
This tool can show all the channels: https://github.com/Acly/hdrv/releases/tag/v0.7
I have attached an example exr file: image_001.7z
Here you can see screenshots from an app which also can only show the first frame channels. The other screenshot shows all channels for in total 4 Frames in the image.

I found by coincidence a small cmd line tool in Natron VFX which I can use for reading out the complete header: Exrheader.exe from the Natron bin folder.

Thanks for this suggestion and for the sample image.
ExifTool 12.56 will enhance the -ee option to read metadata from all frames of a multipart EXR image.
