While

The following text is from the book Art and Advertising by Joan Gibbons. I think the parts of text that are before and after the red sign are showing an opposition and therefore a "while" is required to be placed where the red sign is. Am I right?

Context:

Yet, against the idea that the Pure Gold advertisements represent no more than postmodern eclecticism or historicism, I would argue that the archetypal subliminal content that Jobling and Crowther identify suggests
otherwise, at least in certain cases. Moreover, the claim that a faux-Surrealism is in play assumes that Surrealism, rather than suffering internal disputes and contradictions, was somehow a unified movement, and that Surrealist artefacts always had a deep and genuine connection to the unconscious. The rather obvious way in which Salvador Dali and Max Ernst, for instance, grafted Freudian ideas onto their familial or interpersonal relationships demonstrates that the unconscious was sometimes consciously, if not prescriptively, channelled through some fairly obvious psychoanalytic models rather than represented directly and spontaneously, as might more credibly be argued for automatists such as Masson and Miro.
