My iPad is perfectly straight, and while it lays perfectly flat face down. My smartfolio is kinda warped. So I’m positive my iPad inside the folio will look like this too.
First Things First ! To have any sort of Unbiased and a Real Opinion you need to lay your iPad Pro Naked on a Flat Surface and then ask here, that would give a better picture, with the iPad inside the case it is very difficult to guess !!
