Virused plant?

[NYCorchidman]

My Rosy Sunset 'Pacific Satin' displays serious sick symptoms on most of its leaves. I knew it didn't look good but the flowers were so abundant and pretty to look at, plus, strong sweet scent as an added bonus, and it was only 15, so I thought I would get it anyway and get rid of it once the flowers faded. lol

I don't think it is something common, but I found an online store where I can get it very cheap (I saw one flower shop in West Village who sell this for 125!!! I was like, what!!!!!????), so I'm not concerned much about tossing it, but more about other plants I have in the apartment.

I hope the picture shows the light, almost white, streaking along the veins with some brown spots. There are no bugs, so it's not insect, definitely not bacterial or fungus...so, it's virus or chemical burn from spraying(also I think is not likely as it doesn't look typical of burning from spraying).
Any advanced knowledge, please???
