It appears the pillars are supposed to be spot lit too, so I hope that they were just waiting for them to be finished before putting in the new lighting and ceiling.
I hope.
Another hope is that they use the softer fluorescent lighting in the station, similar to Bessarion when it first opened. That was a huge pet peeve of mine was when they replaced the soft white fluorescent with the harsh bright white kind... it completely changed the feel and design of that station - for the worse, of course... the reds and yellows never looked the same again.
