About 14.3 mpg? Horrible.
In general, 5-8 liters per 100 km is considered a good fuel efficiency, 8-12 liters per 100 km would be average, and more than 12 liters per 100 km would be considered a relatively low fuel efficiency.

Phew, I don’t feel so bad now. After break-in, spending some time in sissy (eco) mode, I was near 19mpg. I averaged 20.5 in my 2021 IS 350 FS DHP, so I was impressed.
I now mostly drive in Custom (all performance settings) or Sport+ and I’m down around 17mpg. Loving every minute of it, this car is hard not to drive fast.

That is a good point, but that applies also to every single vehicle. To me, I would want my IS 500 (if I were to buy one) to be about 2-3L/100km more than my IS 350 (AWD) all other things being equal. In other words, if I drive it the same way, in the same environment and such, I would expect it to be more, but not ridiculously more is what I was trying to explain. But your statement is totally fair, if I start really having fun with it on some days, I can't expect the fuel consumption to be comparable
