Movie mode is definitely not almost the same as having f.lux disabled, or set to 6500K. I think it's basically 4000K but a little brighter overall. It's very close to the 4100-4200K setting. You have to look very hard to see any difference. If you set your Daytime and Sunset to 4100K, and Bedtime all the way up to Sunset Only, that should be close enough for "permanent movie mode".
