I think after 1-2 months. Because first we need some time to produce high quality equipment. And anyway average quality of products in cities still to be 1 first time. I bet first products with quality 2 or more will be in natural food production.
You right. Quality 1 goods make good profit. And much easier to make brand instead of quality because brand also allows you to increase price. But high quality allows you to produce more goods at the same size enterprises + high quality products cost much more than 1.0 quality goods.
P.S. if you look reports of different goods in cities you'll see that their price reduces very fast. And soon we wont get so big profits with 1.0 quality of goods.
P.S.S. I'm already trying to produce 2 quality cows

I heard much about this fact and I tried - so technology bonus is about +3-5%, I think it's very little and insignificantly. For example my factory (2000 work places) outputs 500 furnitures per day, with 2 technology it will output 515-525 pcs and I think it isn't worth to purchase 2000 2+ Q machines and get +20pcs, not profitably
Although on high levels it will be at least noticeably, but it won't be soon

In 2 days I'll begin to breed Q2+ pigs too
But here is a problem.. no plantations with high quality grain ((
