Cattleya suspicion of a virus

[KatKate]

Hello,
I have received a Cattleya Little Treasure on the 07th April 2021 from a known nursery in Switzerland. Already upon receipt I noticed some dark spots on the leaves which I attributed to some minor fungal defects. The flowers were very beautiful.
However upon observation, as of today, I see that the spots became more pronounced and there is some yellow patchiness that appeared on one of the leaves and around one spot on another one.
According some of my knowledge that pattern might be indicative of the CymMV and not fungal infection.
I am searching for an expert opinion, please, on how to continue with this plant, I would appreciate it very much.
Due to a lack of space this cattleya was sitting next to several other orchids in my collection during the first 2 weeks, which is not that good, however I watered them separately. Hopefully there is no risk for the other orchids.

I have seen lots of opinions on whether to destroy the suspicious plants, frankly speaking I am hesitating...
Thank you very much in advance for your input!
