Those 35mm shots don't exactly match either version, but the overall gamma and balance looks more like the wowow to me. Here is an ebay auction for a clip from what appears to be a more balanced print:

Definitely a better match for wowow, especially in the lighter areas.
I don't know if a 35mm press slide is relevant, but this matches wowow color exactly:
The 2 versions aren't really that different in color in daytime scenes (unlike the DVD). The blu-ray has an added brown/orange haze that affects lighter areas, dulling whites and reducing contrast. Saturation is a bit too high. Add to that blown out skies and other bright areas and you get an unpleasant image in many places. Darker scenes look worse, flesh tones are much more orange. Indy and Marion look like oompa loompas in the scene on the boat and during the ark opening. Reducing saturation and adjusting brightness and contrast makes the blu ray look better, but you can't fix shots which are blown out because the detail is just gone.
In the screenshot of Indy with the shovel you can see a slight blue tint to the sky on that lightens as you go left (it's backwards). The blu ray is all white, the wowow has subtle the blu transition.
I wish there were some caps to compare the ark opening sequence, that looks the worst on the blu.
