Could this be a work of virus??

I recently purchased two vandas in vase.
Both plants show some minor streaks on the flowers.

The "blue" flower has the largest streak along the center near the end of the petal. On the back side of this same spot is the same large streak. 11 O'clock direction just to clarify. I know the white "vein" near the center of the flower is normal.

The pink flower has smaller circular mark that looks like watercolor paint that has been smeared, this type of marks also appear in greater numbers on the back of the petals and sepals.

Experienced vanda growers, is this common and normal for vanda flowers? or is this something I should worry about??
