Wait a minute here. The one on the right is the "HDR", combined image? I am seeing more blown whites and more crushed blacks than the original exposure. That image has contrast or curves adjustments that you aren't telling us about. You are supposed to be able to achieve more detail, not less so this comparison is misleading when other adjustments are introduced that negate the increased data in the highs and lows.
