I would have a hard time justifying TIS with Techstream because I would not use it much. I do have an annual TIS account for service manual information, and I do use it quite a bit for someone who does not repair cars for a living.

Just talk to a technical trainer of toyota/lexus and he told me the steering ecu has the ability to self calibrate.
driving today was really nice a lot stiffer than I used to
Did a 100mph test and the steering wheel is much better/stable

I went from 2006 to 2011/2012 Fsport ecu and the difference is more than noticeable, so going directly to ISF2011+ would even be better.
Its hard to explain about the road feel, the different mapping and power assist does feels nicer, but better response and road feel, I could indirectly say yes. See it as, a better assist on each steering angle than before.
