In Theory I have to agree with you. Exporting with current settings should be lossless. But in experience when I export in that manner and again using the animation codec, the animation export looks noticeably better. I do not understand it, but have taken the taste test multiple times.

Using QT’s full screen playback is a good option.

Thank you for your advice. I hope I did not sound like I was arguing, rather I just wanted to share my experience.
