Canon EOS 70DN Basic Instruction Manual page 495

Color space (p.155)
You can select either sRGB or Adobe RGB. Since the camera's LCD
monitor is not compatible with Adobe RGB, the image will not look
very different when either color space is set.
Peripheral illumination correction (p.146)
If [Enable] is set, the corrected image will be displayed. If the effect
is difficult to discern, magnify the image (p.329) and check the four
corners. The peripheral illumination correction applied with the
camera will be less pronounced than with Digital Photo Professional
(provided software) and may be less apparent. In such a case, use
Digital Photo Professional to apply the peripheral illumination
correction.
Chromatic aberration correction (p.147)
When [Enable] is set, the lens' chromatic aberrations (color fringing
along the subject's outline) can be corrected. If [Enable] is set, the
corrected image will be displayed. If the effect is difficult to discern,
magnify the image (p.329).
Distortion correction
When [Enable] is set, image distortion due to the lens
characteristics is corrected. If [Enable] is set, the corrected image
will be displayed. The image periphery will be cropped in the
corrected image.
Since the image resolution may look slightly lower, use the Picture
Style's sharpness parameter to make adjustments as necessary.
