It bothers me when a new creative work tries to adopt a distinct historical style without understanding its form, structure, context, constraints and motivation. Without that understanding it's just derivative imitation which might evoke echoes of the original but can never match, add to it or take it new directions.
While it may sound odd to want new pixel art to be "authentic" in the same way as new music should respect the structure and form of styles like ragtime, blues or jazz, I think it applies equally. The skilled artists who hand-crafted pixels to look their best on CRTs did specific things to leverage CRT bloom and blending, scanlines, composite color artifacting and interlace dithering.
