I recently got the Zeiss VP 8x25 and attempted to compare the glass quality with the Victory SF 8x42. I can tell either the glasses or the coatings might be different. The color on the SF 8x42 is more vivid and richer and the contrast is sharper. Could be different because the difference in apertures and light volumes as well. The question is "Does Zeiss use the same glasses on the VP and other Victory SF 32 and SF 42 ? It could be different since SF is made in Germany and VP x25 is from Japan.
