Which Vandas Have Spots on their Leaves?

[NYCorchidman]

I noticed that my Ascofinetia Cherry Blossom and Neostylis Pinky have dark purple spots and marks of random shapes.

I just recently bought Vascostylis Pearl Cooper (Rhyncostylis x Vanda Pralor).
It is mostly plain green but I notice that a couple of leaves have some black spots. They are not sunken and do not appear to be the dreaded this diamond fungal diseas spots that are all too common on large vandas.

So, I'm curious.
I don't think Rhyncostylis is spotted. At least the ones I saw did not. Maybe it varies since my neostylis has spots but neos do not have spots.
