Web screenshots:

Option Display original photos does not affect

admin/system-settings?isOpen=image QUALITY=100 setting makes the situation better, however it's still much worse then the converted JPG

Could you share an example image?

I would love to, but github does not allow such large files to be attached 😅. I suddenly remembered that I have a dropbox, decided to use it link to the source files
I made a different image to compare: HEIC original, JPG original (adjusted camera settings) and JPG converted from the HEIC original

Tested in Google Chrome:

I also have the same issue.
*.HEIC original image won't load on web client (Chrome v124), the preview image is displayed instead.
I already turned on "Display original photos" knob on web.
Immich Server 1.102.3 (docker)
update: it seems Google Chrome does not support HEIC images, so I think this is expected behavior.

I tested and this isn't actually a bug. It's just that HEIC isn't a web-compatible format so we never load the original, whereas we do load the original on zoom for JPG.

Could it be possible to add HEIC support for Safari? Safari 17+ supports HEIC.

Sure, I made a PR for it.
