It wouldn't really need this extra performance.

When docked, the Switch goes from 720 to 1080p. This is 2.25 times more pixels. When docked, clock rate goes from 302 to 768 Mhz. This is 2.5 times more ops. This design means that developers can write the game optimized for 1080 and 720 will perform more or less the same without any modifications.

Increasing the power envelope for docked mode would only work if developers had to put the effort of selectively toggling some effects in portable mode and actually profiling the game for both 720 and 1080 separately. That's a lot of extra development costs for what I can only imagine to be a modest perf gain with better cooling and clocking higher.

The memory bandwidth only increases by ~20% by docking it. Which is why Breath of the Wild actually performs worse when docked.
