Peppercorn SW 7674 is the lighter, more neutral charcoal, with an LRV of 10 and a faint cool undertone that comes across as a composed dark neutral.
Cyberspace 2124-40 is the deeper, cooler dark with a blue-gray undertone, with an LRV of about 6 and a moody quality that shifts between charcoal and blue.
They are cross-brand (Sherwin-Williams versus Benjamin Moore). Peppercorn is a reliable neutral dark; Cyberspace is a blue-gray that reads differently in different light. The 4-point LRV gap and the undertone difference are both meaningful. Sample both on a photo of your room before you buy a gallon.
