I'm noticing a lot more splotches and marks on the bridge carpet. Such as when Data falls to the floor in Justice.
And when Data pulls the chinese fingertrap off his finger in Last Outpost, you can clear see that the makeup has come off to reveal his normal skin color.
Little stuff like that - that's what CG color correction should be used for!
That's exactly what TNG on BR should be used for. Color correct and digitally 'erase' errors in the sets...erase marks, make the monitors more 'alive', erase those black covers on the back stations, correct makeup rubbing off, etc. They should've made the monitors on the TOS bridge look more alive rather than as the gel sheets they were.
