Preview zoom / original quality

Running seafile 8.0.5 on debian buster.

Currently when you click on an image it opens preview and you can zoom in with double click. Is it possible instead of the reduced quality in preview to have the full original file (as nextcloud appears to do)?

As far as I know the only way (outside straight downloading the image) to see the original file is to click on image → open in new tab → open image in new tab.

I have tried to increase THUMBNAIL_SIZE_FOR_ORIGINAL to ~ 2K but still it won’t reach the same quality.
