If you want no format conversions, then you don't want a compositor in the way and should use the DRM/KMS APIs directly. Both labwc and Wayfire on Pi4 will use OpenGL to composite all screen elements together, and I'm not sure if that can output RGB565.
Even then the pixel data goes through the HVS (Hardware Video Scaler) which will expand any content to 12bpc and drop the bitdepth on the output with optional dither.
