DD, thats as may be, but I am not a member of amazon prime, nor am I likely to become one, I don't watch much TV in the daytime at all, I only really watch two regular shows, TOS and voyager, and of late I've just kept it on and started following the plot in the series 'lost in space', an old scifi, quite unusual in that part way through it made the transition from being on black and white film stock to technicolor, and the change actually occurs midway through one of the episodes, which until that point had been monochrome, and suddenly halfway through one episode, it transitions to being shown in color.
That cannot be a common thing at all, for films or shows to be from the transition period between black and white, and color film, and I should think it even less common for them to be filmed in B&W and then the same series turned over to being rendered in color.
