Hi grasshoppa!
Without going too deep - the WireRemoval node starts off with a soft repair and gradually re-introduces more and more high-frequency information (usually the grain). The control for this is the detailLength control. When set to 0, this should give you a very soft repair. As you raise it to higher and higher values (6 being my favourite, for some reason) then the grain starts to reappear in the repair.
After a little playing, you'll soon get the idea of what values give you back everything that isn't wire, without starting to bring the wire itself back.
The filtering that puts information back onto the soft repair is going to behave differently depending on the contrast of the input, so I'd expect it to behave differently depending on whether you LogLin or not first. Or, to put it another way, the detailLength setting is probably going to be different depending on whether you work in log space or not. If you leave the setting along, it may prove to be too soft in one space and too 'hard' in the other.
The next thing is the repair outside the matte region. This looks like a bug. I'll get The Foundry support team to log it. However, it's most apparent on my example here if you have the sincFilter option turned off. The sincFilter option should usually be on - there's very few things that look better with it off, although leaving it off does speed up processing. while you're trying to tune the wire position and width settings.
If there's something specific about your footage that still seems wrong to you, then we'd be happy to set you up with an ftp location at The Foundry where you could let us see a frame (or a fragment of it, if the full content needs to be withheld). Let me know!
Best wishes
Simon

If I use a loglin conversion then I get quite a contrast in the removed area.
I see that a much larger area than my wire-matte has been modified.
