Adaptive brightness too dim on 9.0.8

[fonebone2]

I have had my OP6 since the week it was released and have dirty flashed every ROM till 9.0.8. Adaptive brightness was always too dim in earlier versions, but seemed to get better with 9.0.7. I finally did a clean flash when 9.0.8 was released, and now adaptive brightness seems too dim again. Is anyone else noticing this, or is this more likely something to do with the clean flash?
