Paph Lynleigh Koopowitz - Black patches on leaves

[SouthPark]

CH - it really does appear to be mainly in the dark green coloured patches - regular darker green areas.

I can't say for sure, but I'm inclined to go toward burn.

The left-hand side of that leaf has some appearance of carbon residue ------ like after we finished a barbeque on a bbq plate.

Were the leaves exactly lke this when it arrived?

So far - doesn't appear to be disease or under attack though.
