I would expect neither of these are photos and that they're Photoshop templates.It looks like a final player issue photo on the Essendon shop site. No red on the inside of the collar.
On the Collingwood site it looks like a photo of a retail guernsey. There is a big white part underneath the number box (where the Emirates logo is).
However, I take your point on the Red inside the collars.
