I'm investigating this for a few weeks now and I just have to conclude this is a LR issue, but I'm not a 100% sure.
I potentially rendered my timelapses of the last couple months in a degraded quality.
Here is the deal:
A sequence at blue hour with a very fine gradient in the sky, perfect conditions for color-banding if the workflow at any point goes into 8bit territory.
Shot on the Sony A7R3 (14-bit compressed raw).
TEST 1: LR Edit with no noise-reduction-> TIFF16bit-> AE (no banding visible, covered up by noise)-> NeatVideo (banding appears after denoise)
TEST 2: LR Edit with no noise-reduction-> RAW (with metadata) into AE (no banding visible, covered up by noise)-> NeatVideo (banding appears after denoise)
TEST 3: LR Edit with strong noise-reduction-> TIFF16bit (banding visible in Photo viewer already)-> AE is the same
TEST 4: LR Edit with strong noise-reduction-> RAW (with metadata) into AE (banding lightly visible)-> NeatVideo (just for testing, makes no practical sense-> really strong banding again)
My conclusion is, that the whole raw-pipeline of LR/Camera Raw is not true 16bit, or that my raws from the camera are not 14bit.
I add the raw files with metadata if anybody wants to try to replicate this problem:

Running LR 11.1 (to prevent current issue of exporting crashes) and AE 22.5.0
