Maybe, maybe not. Sometimes my digital camera exaggerates contrasting edges on lilies, for example, on the trumpet Tropical Isle. Other times my photo looks more correct. The point is, when the color does not come out right they fail to correct it. Better to fool the customer into buying it in my opinion.
Both Hotline and Millesimo are registered in the kavb and Millesimo is also registered in the RHS lily register. They have different registrants, hybridizers, dates. There is a slight difference in color of the edges according to the comparisons to the RHS color guide. Hotline is described as shorter and with a much smaller flower (~7.5 inches vs. ~10 inches). All of these details are things that don't show up in vendor descriptions, nor discernible in photographs.
