Tkinter.BitmapImage s are one-bit -- it would have to be a Tkinter.PhotoImage. The options for file formats are GIF and PGM/PPM. PPM is the only of those that supports TrueColor. It would have to be able to be generated efficiently enough from pure Python (seems possible, but I haven't tried yet).
My bigger concern, though, is that there seems to be no way to update just a subregion of the PhotoImage from pure Python. I see that the C code in _tkagg.cpp can do this. Does that actually get used or is it always a full image?
