Could be. Partially the fault of the SPD and the Greens for not changing the narrative. If they had both managed to gain new voters rather than leaving more people at home, they could have had the majority (27,000 voters equals roughly 3.3 percentage points, from my rough estimate looking at the Linke number).

P.S. FDP now at 4.7% at the 23:38 results. They're definitely not getting in.

The 2.6% to the 'other' category is split between DVU, Kusch, and other parties. Highest results for the DVU in 8 out of 17 boroughs that have final results is 1.8%, most under 1%. The far right is out of the game.
