D54 does not look blue, it looks reddish. Also, it's important to differentiate between D54, which is a point on the CIE chart, and a CCT of 5400K, which is a line on the chart, and at one extreme can look blue. Regardless of the rating, if you measure one of these lamps that look blue, it will have x and y values that are not D54 but more towards blue. (I don't think that there is a D54 standard illuminant and I am referring to x and y values that would correspond to one.)
Using D65 calibration is one of the essential components to have accurate colors for consumer sources. If you use a different white reference, you don't get a film look, just inaccurate colors.
