With LRVs of 33 and 33, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — River Gorge Gray's yellow and red character against Dusted Moss 1's warm — becomes most visible against white trim or in morning light. With a ΔE of 2.3, the difference is subtle — you'd need them side by side to reliably tell them apart.
