Is picture quality worse if PS 2 software is started with PS 3?

PS3 has a compatibility function that PS2 software can play, but for now it seems that image reproducibility is not so good. If you are just playing normally you may not be bothered, but you can see the difference clearly from the comparison video.

Details are as below.

There are also large images that are easy to understand. Here we use the same TV and cable.

This is also the site of people who compare images. There seems to be some software with little difference.
