Its look like when you stitch panoarama sphere with other good programs the quality is better then withe the internal program from dji.
I use Panoramastudio 3.5 Pro. and for view i use FSPviewer
With program do u use for stitching and viewing?

Hello there Andre vd Weide. Good day and thank you for the inquiry. Since this is a 3rd party software to stitch photos that you have captured using your DJI drone. I hope that you will get the best recommendations and information from our fellow DJI co pilots on what is the best editing software to do the said process. Thank you and fly safe always.

I use Panoramastudio or Lightroom to stick HDR pano's.

PS,   If you want to host the pano yourself check out https://pannellum.org

Thanks
