CymMV in Bulbophyllum?

This has shown up recently in some of my bulbophyllums, and I was wondering if it could be CymMV. It seems to be occurring in the younger leaves especially.

I'd have a look into the fungal leaf spots direction as a first impression.

For viruses only a test would be an indication, not just symptoms.
