Will games on the 3DS XL look worse?

since the screen is 90% larger than the regular 3DS at the same resolution, will the games look much sharper on the 3DS as opposed to the 3DS XL?

Yes

I am going to guess: yes!

Does anyone here know if the same happened with the move from DS to DSiXL?

Like running 800x600 on a 24" LCD monitor with no AA.

Actually, like running 400x240 on a 4.88" screen with no AA.

On same games you could tell and on some you couldn't.
