Atomos Shogun 10bit vs GH4 8bit 4K - RAW footage (can you tell the difference?)

More info at: http://tomantosfilms.com/
Just started testing out the 4K 10bit recording on the Atomos Shogun versus the internal 8bit recording on the Panasonic GH4. Can you tell the difference? Cuz I'm having problems.

Next video will be the same test but with a heavy color grade applied to see if the 10bit holds up better in grading.
