The first one looks natural to me. The second grade looks like a 1st year film school grade where they think the full range has to be used at all times. In a soft well lit room the contrast would never be that high.
The intention was clearly to make it look like a warm interior, adding all those grungy green tones make it look like she's standing by a window. I dunno the context of the room, but number 1 looks way better to me..
Edit: Final thought - crushing blacks like that, from a game perspective means you may miss details that may have been meant to be seen. But power to you! Options are always better.
