Incorrect Content-Type for webp image in webhook headers

I used a webp image for main product image while creating a product in Shopify products. A webhook is triggered after creating a product. All the content in the webhook payload is good. The issue is while fetching the image hosted in cdn.shopify.com the content-type is image/jpeg instead of image/webp. Due to this behavior the image file is received as a jpeg file instead of webp.

 

Expected: Correct header content-type: image/webp for webp images.

 

Example request response - used fetch(image-url):
