Not even close. CRISM wasn't in orbit, remember. CRISM can do two things that THEMIS couldn't: it has much much higher resolution (so it can spot deposits with smaller spatial extent) and it's near-infrared, which makes it much easier to pick up the presence of water and hydroxyl, which is how you identify the presence of clays.
