At least in broadcast/cinema, no one uses CNN for debayering, because why would you? In cinema, you just use a 6K sensor and use conventional debayering for a perfect 4K image. Even the $2000 Sony FX-30 ships with that feature nowadays. Combined with a good optical low pass filter, that'll also avoid any and all moiré noise. In broadcast, if you worry about moiré noise or debayering quality, you just buy a Sony Z750 with a three-chip prism design, which avoids the problem entirely by just having three separate full-resolution sensors.
