Would this be a definitive CymMV test result?

After so many months, what might be the best approach to this is to write the vendor and let the vendor know that the orchid showed signs of virus, you confirmed the virus, and you just want to warn them that there is a possibility that some of their orchids might be infected. Include the picture of the test. Write it with the intention of trying to be helpful. Don't ask for anything. Hopefully, they will offer to compensate you for it.

Most good vendors of plants have an unspoken 'thirty-days guarantee' and, after that, they feel that whatever has happened might be due to the buyer's care. Mosaic Viruses are easy to transmit (studies have shown that brushing an infected plant with a tool and then an uninfected plant with the same tool can transmit the virus) and the time for expression in the new host depends on the host plants ability to defend itself against the virus.

Many years ago, when I first joined an Orchid Society, I took a Cattleya I'd grown for years for the show table and someone set their Cattleya against mine so that the other Cattleya's leaves and pseudobulbs were pushed into mine. The flowers of that orchid had color break and I isolated my orchid upon its return home. The orchid had always grown and bloomed twice a year, like clockwork, but the next set of new growths were late, grew more slowly, and, when it bloomed, the flowers had color break.
