thanks for helping! not sure a video would help, but here is what you see on any single product page:

every jpeg images from uploads is correctly served as webp, but not the larger one used for zoom over the product. below is the element:

the best solution would be for WordPress to finally handle webp natively but I am not a decision maker. webp is still a new format only used by 95% of all mobile and desktop web browsers in 2023.

I really don;t know which browser in 2023 cannot handle webp and honestly, the next step is simply to modify your single-product.php functions to server webp natively and be done with it. But hopefully we can figure out a more generic approach that can help others?
