@KaveeshaKul,
We have reproduced and investigated the issue. To render color emojis correctly, Segoe UI Emoji must be installed and available in the environment where the conversion is performed. Replacing this font with Noto Color Emoji and Symbola, or another font results in incorrect or monochrome rendering.

During our investigation, we also found that one particular emoji is not rendered in color even when Segoe UI Emoji is used. This issue will be fixed in a future release. We will notify you when the fix becomes available.
