Exist 'a tweak' or qn option for resize screens on new 3DS/2DS XL with 3DS games?

[GBAtemp]

Hi,
I like my New 2DS XL,but i have noticed that if i hold it near to my face (like a smartphone) i notice too much the low pixel density and scanlines..
So,exist a way to resize the screen area?
Like,for example,the old DS Games playing on 2DS XL...
If i press start+select with DS games the screen size is much smaller and the pixel density is better.
It could be a great thing to have 'something like that' with CFW,etc on XL screens for 3DS games...
