Morgan has asked me to add this pedigree.
Tonkinese - Lilac Tortie bred to a Toyger Caramel gave a Lilac so it must hide the Toyger - Caramel, as the Caramel predates the release of the spring cats so cannot hide the Burmilla - Lilac Shaded.
So we now have an official start point at least until the original Lilac reveals its hidden which we suspect to be Burmilla - Chocolate Silver Shaded
