Skimming that post shows a lot of people saying that first layer doesn’t affect top layer. What is your definition of z height? We may have a definition issue on our hands here. To me, it means the distance between the nozzle and the bed on the first layer.

I’d be with you on the underextrusion though if the very top layer didn’t look so good. I would bet OP doesn’t have enough layers on top of the infill leading to an artifact that resembles underextrusion.

Sure, on the first layer. We can’t see the first layer here, only the top layer, so it can’t be the z height.

How can you tell that OP hasn’t leveled their bed properly? You can’t see the bottom layer in their picture.

It looks like you can use an automation to trigger something when you leave a location. I would try that.

They’ve actually been trying to do this for years. There were actually a couple years of tests out in California I think. However, there are two big lobbies that always put a halt to it, tax preparation services (H&R Block, Intuit, etc.) and groups that want taxes to be a pain in the ass so we’ll all bitch about them.
