ComboFramePlayer is just an option to show combo points on the player frame instead of the target frame, which is what ComboFrame does. This option is controlled by the cvar "comboPointLocation" and it defaults to using ComboFramePlayer. There does not seem to be a GUI toggle for it.
These were taken when using Anticipation, at max combo points:
ComboFramePlayer
ComboFrame
Personal Resource Frame (aka ClassNameplateBar)
