Comment (by Balling):

 >The resulting Y code values are equal to 943. They should be equal to 940

 Yes, you are correct. Indeed, in RGB as it is full range in png, we have
 the 100% white at 65535 (counting from 0). Though again, the source of the
 image is using 2.2 gAMA (not even sRGB) and yuv will be assuming BT.709
 transfer...
