Yes, though a SKU doesn't specify the memory chips, the QVL applies only in particular situations. (higher speeds and capacities)
QVLs aren't complete lists. RAM makers send kits for checks, but they rarely include every product, especially if any are missing. Even when a kit appears on the QVL, it doesn't ensure full coverage, since testing isn't done for every possible setup a customer might use—like various CPUs or power supplies. Moreover, manufacturers often replace chips in kits without updating the model number or resubmitting. In short, the QVL offers little real value unless the RAM is unusual, such as with high-speed clocks for DDR4. Nowadays, compatibility isn't a major concern unless the RAM is very specialized.
