Don’t know how true that is, but if you want to believe in an actual Galaxy Note 4 running the latest TouchWiz firmware, then here is a port that will take your device to Marshmallow. It is based on the official Samsung TouchWiz firmware and has been reported running with no major bugs or instability issue. So remember, this will only work with devices running Snapdragon processor and not with the Exynos ones and is meant for the N910P variant. So if you are looking forward to flashing it, then you better backup.
To install it you will need to install an engineering bootloader and the Baseband from PB5 firmware before you make it work via TWRP recovery.
