DPP and HIF HDR PQ

In DPP, I experimented with HDR PQ. Since most web browsers will not display HIF, I then attempted to convert the HIF to JPEG. I am attaching examples of the results. I like the result produced by macOS Photos and the result produced by GraphicsMagick better than the result produced by DPP.

The HIF file saved from DPP looks really good on my iMac screen in the photos app, much better than in DPP. Since I have a screen capable of displaying HDR, it would be easier to see the edits in DPP HDR PQ mode if DPP would use the capability of the screen instead of converting to SDR.

Is there a way to get a similar export to JPEG result using DPP as when using macOS photos app or as when using Graphics magick? Thanks in advance.

I found more information at https://www.color.org/whitepapers.xalter  which is a standards organization and I hope this might be of interest to others.

Since JPEG is SDR only and the HDR PQ standard does not permit changing the curves, I increased the input dynamic range in DPP while still creating SDR output and did not do the HDR PQ in DPP. The result is SDR and JPEG so that it may be displayed in web browsers. The attached image in this post was compressed more using graphicsmagick so that it would be small enough to upload, so it does not have quite as much information as a JPG saved from DPP at quality 10. I used tone curves in DPP to approximate what I saw on a HDR PQ display in a JPG that may be viewed in a web browser. Another approach to this would be to always photograph this bird at -0.67 EV and brighten later in DPP.

I used "exiftool -G0:2 -h IMG_3356c2.dr4" to get a record of the edits I have done in DPP.
