Dark spots leaves

[missfitxo993]

I bought mokara today and it was directly exposed in sun. I asked the caretaker why no net and she told me that mokara blooms frequently if direct exposure but leaves have dark spots. So I checked almost all tge strap leaf orchids and it has dark spots and i believed her saying its not fungus or a problem just sunburn. But i want to ask the opinion of the hobbyist and grower here.
