Approach kept us high on the arrival into CHS. ATC issued a late descent and gave us and we read back an altimeter setting of 29.94. We transitioned to the RNAV RNP Z 15 in VMC conditions. We stayed on the vertical guidance until about 500 ft., we had the runway in sight but we looked low. We couldn't make out the PAPI until 500 ft., with the morning glare. Once we could, it confirmed we were low. We checked the descent and landed with no further issue. After [we were] on the ground we realized the altimeter was 29.84

While flying the AMYLU3 arrival into CHS airport, we picked up the local weather/ATIS information. The altimeter setting was 29.84 inches. We were then cleared for RNAV Z RWY 15 approach. Shortly after, we were transferred to CHS Tower. The Tower Controller advised us that ATIS was current, and the altimeter was 29.94. We both heard the transmission and the Pilot Monitoring read back 29.94. It did stand out to me that we were had a .10 difference. We configured to standard profile but inside 1,000 ft. while on glide path we looked a little low. Around 500 ft. we had roughly 3 red lights PAPI. Since I was hand flying, I leveled off. Transitioning from the outside view to the glide path. I announced leveling off or possibly correcting and the Captain acknowledged. After 500 ft. it was obvious that the outside view was the correct or safer path.
