Image quality wrong

Hello fellow website-owners,

Theme: Woodmart /with/ woocommerce and AJAX product filters

My website has one main issue: the images in the woocommerce product gallery are NOT good quality on mobile and desktop – this happens when u click ”enlarge” (the white button, sorry its in dutch). the image becomes pixelated and zooming in is terrible quality.

U may notice that on desktop the image looks excellent when not clicking the button, that is correct, But on mobile view the images themselves are not 100% quality, not a good resolution!!

I added some settings (sceenshots) to let yall see what i possibly do wrong.. i have tried regenerating images with differend settings but it just does not solve the issue.. I also have tried using Imagify (plugin) but does not work aswel… it is very frustrating, please someone help me – i will thank u endlessly.

Thanks in advance, all help is welcome.
