AD8174 output swing with unity gain

The AD8174 datasheet specifies a minimum output swing of +/-4 V @ RL=1 kOhm. The input voltage range is +/-3.3 V, which is fine with G=2. However, is the input range the same with G=1? In that case, does this mean that the output swing is limited to +/-3.3V with a gain of 1?

Additional question: what would be the typical output swing @ 50 mA output current (with G=1 and G=2)? Is there an easy way to compute this?
