Even if the display has a built-in "blue only mode" (no filter needed), it will only work if the blue primary is accurate, so even if there is a "blue-only" mode, your final adjustment is still "by eye" with all 3 colors working.
Yes, if the blue filter method fails, you just view content and tweak color and tint until everything looks about right. You can't use crap sources though... Blu-ray movies, decent ones they spent some money on to get the technical things correct are best.
The REAL way to get accurate images on a video display is to calibrate the display. Twiddling the basic user menu controls isn't really calibration, per se. Calibration requires a meter, calibration software that is compatible with the meter being used, and a video pattern source (disc or video signal generator). Your options for calibration are to spend money on the gear needed to perform calibration and study and practice for 100 hours or more until you have the background and skills developed so you can perform a reasonably good calibration on your TV OR hire an independent professional calibrator who is likely to charge $300-$500 to spend 2.5-5 hours calibrating your video display. 3D calibration takes additional time and would be on the high end of the price range, while 2D calibration only would be towards the lower end of the range and shorter time required. 3D TVs are just like 2 TVs that just happen to be in 1 "box"... nothing you do for 2D calibration applies to 3D calibration so you have to do two complete calibrations to get 2D and 3D calibrated to be as accurate as they can be for both formats.
