It depends on how calibratable your TV is... many 32" models have very limited calibration controls. I don't know the U3 series so can't say one way or the other.
What happens if you select the next "higher" color temp setting (like warm1 or Standard or neutral or whatever it might be called)? Are images objectionably too blue?
A calibrator would likely measure "white" using the 2 closest color temp settings and pick the one that's closer to d65 to use as the calibration starting point. So if Warm1 measures 6000k and Neutral (for example) measures 6800K, the calibrator would almost always start with the "Neutral" setting.
How well or even whether your TV can be calibrated is determined by the controls available to the calibrator. These days, most of these controls are in the user menu.
