so what does this icon actually do? 👑

She verifies if pre-Raven2 RV devices add RV-specific S-swizzle modifiers and non-constant-encode DCC modifiers. That's the whole vibe check — pre-Raven2 RV hardware, S-swizzle modifiers that are RV-specific, and DCC modifiers that are not constant-encode 🌈 ngl if you're deep in AMD display plane modifier land, this test is your bestie 💀
