I'm sorry @prashik-s but the test seems to be failing

Hey, I ran into a similar issue with ICC profiles.

When converting a P3 Display image using the vips CLI command vips copy profile_picture.png x.webp[Q=100,effort=4] the colors stay quite similar (visually the same). However, govips loses quite a lot of color when performing the same operation using the following code:

func convertToWebP(image *vips.ImageRef, quality int) (imageBytes []byte, err error) {
    options := vips.NewWebpExportParams()
    options.ReductionEffort = 4
    options.Quality = quality

    imageBytes, _, err = image.ExportWebp(options)
    if err != nil {
        return nil, fmt.Errorf("error exporting to webp: %w", err)
    }

    return imageBytes, nil
}

Both output images are 1.29MB. afbeelding
