GH2+LR4=RAW Headroom?

I am totally stunned at what LR4 can do with GH2 raw files, typical example!

White sky, blown, try metering differently, messes everything, in fact at the time this seemed OK, in fact this was the sky, I thought.

So original,

best effort in recovering the sky and keeping the picture balanced in lr3.6

still lr3.6 but applying an nd filter to see if the exposure in the sky can be pulled and whats there.

Now lr4, the sky definately can be pulled and there is headroom, quite a lot, even blue bits of sky, incredible!

Some final tweaks, just on the wooden scuture face! Note the sculpture is about 15ft high. 14mm used as a 25mm wa! 16:9 ratio.
