The default option doesn't include settings like White Balance, Exposure, Sharpening, Lens Corrections.
PixelPeeper presets are intended to be generic and those settings are often specific to the photo.
If you need these settings, you have the option to download an "extended" preset file.
If you want all setting, including masks, corrections etc., you can download the "Full XMP Settings" preset.
Please note that this version of the preset can't always be imported correctly into Lightroom. It's often
because such presets contain settings that depend on 3rd party plugins or looks installed on your computer.
