A tough call Kathy,
the image is in insufficient depth to accurately comment,
you will need to scan at say 400-600 dpi
and isolate perhaps the bottom RHS bunch of flowers.
You could be right, but there is depth of shading where the grey is supposed to be, and it may be, the grey has been washed out.
One has to be vigilant before calling an error.
but for your sake I hope it is
