Seek out the 4K, 60fps Director’s Cut. Watch it on a screen with true black levels. Pay attention to the red saturation. You will not be disappointed.

Here’s a general review based on typical viewer feedback for this scene, since I cannot watch or verify specific adult content directly:

Pros:

A frequent flaw in lower-tier productions is poor audio. In the Pretty Girl in Red scene, PKF uses directional boom mics and lavaliers, mixed to 5.1 surround sound. The rustle of the red fabric and Katie’s vocal range are captured with studio-grade clarity.
