If anything I find the opposite far more common, the whole "it looks great on the small screen but not so much when you blow it up on a big TV".
I very doubt anyone would be complaining if in docked mode the GPU ran 20% faster at the Shield's 921MHz clock, allowing for better resolutions in TV mode, where it's more often compared unfavorably to stronger TV-only consoles.
As a I said, this very thread already gave portable mode a negative aspect against the current docked option. Imagine how more negative it would be if the disparity were larger.
