My First Officer was flying a visual approach to 17L in DFW; aircraft was stabilized at the appropriate altitude and he continued his stabilized approach to the runway. The aircraft was on a good/acceptable visual glide path to the runway and hit a small area of unsettled air from a previous arrival close to the runway threshold that caused a small settling which cause the PAPI lights to all go red on short final. There were no glideslope or sinkrate calls from the EGPWS before touchdown.  The aircraft touched down in the touchdown zone on speed and with an appropriate sink rate to effect a safe landing.  Be a little more proactive/careful about flying through potential areas of wake turbulence/disturbed air from previous arrivals.
CRJ-700 Captain reported they got a bit low on a visual approach to DFW after a wake turbulence encounter.
