Gamma Correction for Resident Evil 4

[mqhaji]

Summary

• sRGB -> 2.2 Gamma Correction has been added to Resident Evil 4 Remake
• The gamma adjustment slider is no longer by luminance, it is now by channel
• LUT Scaling has been modified to reduce black crush when paired with gamma correction
• DICE ShoulderStart has been increased as it was too low before and gamma correction also lowers highlights

Justification for Changes

• Gamma Correction: The display I was originally using at the time of creating these mods was crushing blacks. Blacks are actually not crushed with 2.2 gamma correction. The gamma calibration menus in SDR also seem to imply 2.2 gamma is expected for these games.
• Gamma Adjustment Slider: The gamma adjustment slider is now an alternative to gamma correction, as emulating 2.2 gamma often looks crushed (though that seems to be the intention of the developers)
