May as well post this in here as some of you folks are afraid to go outside. For those of you allergic to CheatEngine and want Lightning Returns at a rendering resolution other than what's offered I've got good news...
You can modify the executable to replace the resolutions to what you want. Still misses the depth of field resolution and you would be overwriting one resolution for another so not as flexible as using Cheat Engine but if you wanted to replace 1920x1080 with 3840x2160 and fire and forget then it will work.
Regards to scaling, you'd need to select Full Screen as you Display Type and Scale Display Area to Standard to get bilinear scaling (as you get with DSR) but screen shots would only be at your desktop resolution and already resampled. If you wanted full resolution screen shots you'd need to set you desktop resolution to 3840x2160 for example and then you'd get raw, unaltered captures.
Couple of examples bellow.

On a 2560x2160 monitor or less at 100% zoom you shouldn't be able to tell the difference. End of the day none of this is ideal and SE should have enumerated resolutions via Windows and handed this off the game and then none of this trivial fucking about would be necessary.5120x2160 rendering res captured as full resolution with no resampling said:
