Expecting the same calibration targets to produce a visual match between dissimilar display systems is one problem. Solution? You’ll need to alter the calibration targets for one to match the other through trail and error and don’t expect an exact match. Especially if their native color gamuts differ greatly and they use differing backlight technologies. You want two displays to exactly match? Get two NEC (or similar) of the same make and model, calibrate them with their host software products using the same instrument, they should match (the entire idea behind color reference display systems.

I managed to pull my old CG-21 of the moth balls, to serve as a second display - how could have I ever lived without this convenience? Crazy.
Of course, first thing I did was to try to make it "look" like my NEC PA271W. They're both LCD monitors yet, at the same chromaticity and Luminance, they don't look the "same". One is "reddish" (CG-21) while the other (NEC) is "greenish".
Any suggestions?
