The new size is only for images uploaded to Amazon that will be used for their catalog - and doesn't affect the image you use in your book (which I believe means the image in your book file that is marked as cover). See their KDP information at
But then again they have a confusing comment saying that when you publish your book, your cover image will be automatically added to the inside of your book. So do they mean they will take the catalog cover image and use it inside your book instead of the cover image you added when creating your mobi file, or do they just mean that when you create your mobi file it will always include a cover image in the book.
