I don't think so, Lorn. I have had it for YEARS and it has outlived any other Oriental lily I have tried. It is from Judith's Summer's End strain. I noticed that the breaking (if that is what it is) occurs only at the margins and affects only the petals, not the sepals. Still I worry that it is virus because this lily is no longer available (thought it looks like she is selling seeds).
A couple of other things I can add is that we had a very cold winter (for us); long stretches of single digit temperatures, the lowest at my place was 0F. The other nearby Summer's Ends were not affected. Also my lilies are not planted very deep (3" at the most) and I don't mulch.
