NVIDIA just rolled out a quick hotfix update for their Shield Tablet. Apparently there was a color reproduction issue with the display that was introduced by last week's 2.2 update. This hotfix is 2.2.1.

Here's the official changelog from NVIDIA:
  • Display color-space correction
  • Improvements to Netflix experience

Hmmm... color reproduction issue? Is that anything like that silly gold & white/blue & black dress optical illusion which is running rampant across the web?
