When converting images to WEBP format, images may not display in certain environments (especially Mac and iOS) if the color profile is not embedded. This is because a color profile provides the necessary information to accurately display the color information of an image, and if it is missing, the image may have problems displaying.
Furthermore, even when using the EWWW Image Optimizer image optimization plug-in, the metadata should be set to not be removed. This is because metadata contains color profile information.
As mentioned above, color profiles and metadata are important elements for proper image display, and retaining them can help avoid image display problems.
