Something like,

     ffmpeg -i in.bmp -filter_complex
            'format=yuvj444p,extractplanes=y+u+v[y][u][v];
             [y]sr=dnn_backend=tensorflow:model=espcn.model[y-sr];
             [u]scale=iw*2:-1[u2x];[v]scale=iw*2:-1[v2x];
             [y-sr][u2x][v2x]mergeplanes=0x001020:yuvj444p'
             out.bmp
