New Cymbidium aquisitions - health check please!

[LexyBoy]

Hello!

I've had my eye on some Cyms at Homebase for a while as they were clearly overdue to be marked down. Popped in today and found them sitting on a trolley, reduced to £5 (from £20) - I think they were waiting for the very last flower to drop!

I bought two (actually the money went in the charity box as the supervisor couldn't think of a quick way to run it though the till, which was unexpectedly nice for a big chain) and am pretty pleased as they're nice big clumps. I'd appreciate some advice on one though which has subtle mottling on the leaves and spotting on the older ones - I wasn't worried about the spots in the shop but didn't notice the mottling until it was home. My first thought was virus but it doesn't look like virus from photos I've seen - any thoughts? Secondly, is virus worth worrying about for a hobby grower with less than a dozen plants?

Bear in mind that they have been in the shop for a couple of months, in cellophane sleeves and chronically overwatered. I've increased the contrast in the pics to make it more visible - as I said it is subtle but noticeable in good light.
