They are different. The codes on the edge of the film indicate "200 S" for Colorplus 200 and "GB 200" for Gold 200. Colorplus is cheaper, I doubt you 'll find Gold 200 for a quid. I think Colorplus is an older technology colour film so it looks somewhat basic compared to Gold 200 (which itself is older technolody compared to Portra). Is Farbwelt the same as Gold 200, I don't know. The edge markings should tell.
