I spend more time in RawTherapee and just randomly tried different Exposure settings. This is what I got. It is closer, but still not sure how to bring out the surface texture and contrast.
WB: 4000
Exposure:
EC 2.3
Highlight Compression 25
Highlight Compression Threshold 80
Black 940
Shadow Compression 55
Contrast -15
Saturation 19
Adjusted the tonal curve to increase highs and decrease lows (like S curve).
Sharpening: USM, radius 0.8, amount 284.
Edges: Qty 50
